We’ve listed the most popular Frequently Asked Questions below. We hope this discussion enhances your ownership experience.
How should I clean my Callaway’s polished supercharger?
Polished MP112 and MP122 supercharger housings can be polished using a quality metal finishing paste such as Simichrome.
Simichrome or any other abrasive-based finishing paste should not be used on the ChromeCoat surface of TVS1900 and TVS2300 housings. These housings have a special surface coating which will scratch. Ordinary care includes washing with mild detergent and a soft cloth. A top coat wax may be applied to enhance the shine of a TVS housing. However, the wax should be tried on a small section of the housing to determine its effect before applying to the whole unit.
A question that often arises: How to best launch a manual gearbox Callaway Corvette or Camaro? Answer: Judiciously! Start at about 1500 RPM. That’s right, 1500! We’ve found that this is approximately the right rpm for a successful launch. Just try not to overpower the tires. Shift to 2nd a few tenths before you see the 6400 RPM point. For Corvette, shoot for a 1.6 second sixty-foot time.
Alternately, use Launch Control. The Launch Control function included in Camaro and Corvette traction management actually works fairly well for both stock and Callaway applications. It’s especially helpful for drivers without much experience with high horsepower vehicles. We have tested with Launch Control as part of our product development process to ensure that it functions as originally designed.
There are conditions that the Launch Control system cannot monitor, however, including tire temperature and condition, and road surface temperature and condition. When tires are cold, when the road surface is cold, or when the road surface or tires aren’t clean and dry, excessive wheel spin is more likely.
Follow the instructions provided in your Corvette or Camaro Owner’s Manual:
1) Double click the Traction Control button, you’ll see “Competitive Mode” displayed in the Driver’s Information Center (DIC).
2) Depress clutch pedal to floor.
3) Move shifter to first gear.
4) Depress accelerator pedal all the way to the floor, smoothly. Engine speed will hunt briefly and then stabilize at approx. 4200 RPM for Corvette, 3500 RPM for Camaro.
5) Keep accelerator pedal to floor and release the clutch rapidly but smoothly.
6) Hold on.

Faulty Fuse Holder – 2007 Callaway Corvette?
The fused circuit that supplies power to the Magnavolt fuel pump controller is prone to a failure of the early style fuse holder. The symptom is intermittent operation of the fuel pump. These original-style fuse holders should be replaced by the updated version with the WeatherPak-style connector. Contact Callaway Technical Service for replacement parts.
Alternator Pulley Attachment?
The alternator pulley nut is secured with Loctite 290 wicking-type threadlocker. It is worthwhile to check its tightness periodically. For maintenance and repair, use a new locknut each time the alternator pulley is re-installed. Loctite per standard procedure.
Can I retune my ECM for more power?
DO NOT RECALIBRATE YOUR ECM!
The program that controls the engine management system in your Callaway is special and unique to your vehicle configuration. It was installed into your Electronic Control Module (ECM) by recalibrating the ROM (read-only-memory) at Callaway.
The Callaway version of the software, or calibration as it is known, is the only one your car or truck can use. The problem comes when the ECM is inadvertently recalibrated at the Chevrolet dealership during normal maintenance. The GM service department recalibrates ECM’s on all GM cars as a standard part of update maintenance. Your responsibility as a Callaway owner is to not let this happen.
Even though Callaway Authorized Dealerships know this, it is highly recommended that you remind the technician or service advisor when you drop off your vehicle. If the ECM is recalibrated using the standard GM calibration, the car will not run well, and if driven in this condition, serious engine damage may occur. Chevrolet dealers cannot install the Callaway calibration. The ECM must be returned to Callaway to be recalibrated.
In order to make this clear, there is a warning on the cover of the port that accesses the ECM. It clearly states: DO NOT RECALIBRATE!
Between this warning and your knowledge of this situation, we hope that you will guard against this misstep.
Should this error occur, the ECM can be overnighted to Callaway Cars, and we will recalibrate the ECM at no charge other than shipping. Please call Callaway Technical Service in advance for confirmation (860 434 9002).
Driving Tip – Callaway Corvette with 6 Speed paddle shift transmission
Owners of automatic transmission equipped Callaway Corvettes should implement this technique as a standard part of their driving routine.
Perhaps you’ve discovered this already, but if not, try this the next time you drive your car:
Put the car into paddle shift mode.
To do this, simply select “S” on the gearshift and initiate one paddle shift event at the beginning of every drive cycle.
This forces the gearbox to remain in the selected gear even when full throttle is used.
As the primary driver, you probably already know that a sudden full-throttle application, while in the full automatic mode, will incur a downshift, and sometimes a ‘double downshift’. This results in too much power and an unpleasant drive. Putting the car into paddle shift mode prevents the downshift altogether.
It’s better to have the car stay in the selected gear, and use the boost from the supercharger to feed in the power with your throttle foot, as you wish; not as the gearbox wishes.
All potential drivers of the car should also be informed: especially the driver new to the car.
Where can I buy a Callaway Corvette, Callaway Camaro or Callaway SportTruck?
Callaway Cars Inc. has established Callaway Authorized Dealers in the most active market regions in the US and Canada. Please refer to our website’s Callaway Authorized Dealer list. You can take new car delivery at the California or Connecticut Callaway Factory or ask your Dealer to arrange transport. You can also take delivery of your Callaway Corvette at the National Corvette Museum via the RPO R8C National Corvette Museum Delivery Option. If there is no dealer in your area, call us at 860 434 9002 and speak to a Callaway Specialist. We can procure new cars on your behalf from a Callaway Authorized Dealer.
Can I buy a Callaway directly from Callaway?
No. Callaway does not sell complete cars or trucks, with the exception of periodically selling product development vehicles after their test programs have concluded.
I am planning to buy a new Corvette (or Camaro, or Chevy truck). How do I make it a Callaway?
Very easily. Call Callaway Cars at 860 434 9002. Speak to a Callaway Specialist about the details of your order. You will be directed to an Authorized Callaway Dealer for a test drive. When you order your new Callaway, the dealer will specify the Callaway drop ship code. Then your new car or truck will be built at Chevrolet’s assembly plant and shipped on a GM transporter to Callaway Cars’ Connecticut or California plant. You will make all of your purchase arrangements (including financing) with your local Authorized Callaway Dealer. Upon completion, you may choose to take delivery at your dealer or at a Callaway Factory in Connecticut or California. If you’ve purchased a Callaway Corvette, you may also elect to pick up your car at the National Corvette Museum.
I already own a Corvette (or Camaro, or Chevy truck). How do I make it a Callaway?
There are certain criteria that used vehicles must meet to be considered for conversion to Callaway Corvette, Camaro or SportTruck. First, the vehicle must be of the current or previous model year and completely stock, just like it rolled off the assembly line. Second, the vehicle must be completely free from any damage or defects. Third, while there is no specific odometer reading limitation, the vehicle must be as-new mechanically. That means, at Callaway’s discretion, testing may be required to determine the condition of your engine before proceeding with any other work. You would be directed to your local Authorized Callaway Dealer and your purchase would be handled by the dealership, just as though you were purchasing new. If there are no Authorized Callaway Dealers in your area, call Callaway Cars as you may be able to purchase the package directly from Callaway.
Should I shop around to get the best deal on a new Callaway?
As part of the Authorized Callaway Retailer Agreement, our dealers have agreed to charge Callaway’s Manufacturer’s Suggested Retail Price (MSRP) for all Callaway packages and optional equipment. No individual dealer will give you a better price than any other for the Callaway equipment.
Do I have to ship my car (or truck) to California or Connecticut?
Genuine Callaway vehicles are built in Old Lyme Connecticut and Santa Ana California. Then they are shipped to Callaway Authorized Chevrolet Dealers for sale. Alternatively, currently owned cars and trucks that are not in an area serviced by a Callaway Dealer can be shipped to either Callaway facility for conversion. We have transport arrangements made through Plycon Transportation, as their owners are also Callaway owners. Some owners choose to pick up their new Callaway cars and trucks at the National Corvette Museum or either Callaway.
Do I have to use the Callaway Corvette hood?
The Callaway Corvette hood design is an integral part of the Callaway Corvette package, differentiating the Callaway Corvette from tuner-built supercharged Corvettes and providing additional clearance for the supercharger. If you want a Callaway Corvette, you have to use either the standard carbon fiber hood bulge or optional Callaway C16 hood. Some folks, initially, have said they want a different solution. Then they come to the factory or visit a dealership and see the look and quality in person. No one, to date, has rejected our advice.
What are my choices for the hood bulge color?
The Callaway Corvette carbon fiber hood bulge is a clear-coated, natural finish carbon fiber. Contrasting colors may be provided at extra cost. If the optional one-piece C16 hood is selected, Cyber Gray Metallic is used as the standard contrasting color, with Machine Silver used for Cyber Gray Corvettes. We provide customer-selected accent colors on C16 hoods as an extra-cost option as well, but we reserve the right to decline certain color combinations.
How does Callaway develop its horsepower rating?
Engine dyno or rear wheel?
In order to establish advertised power ratings, peak horsepower and torque are recorded during final testing of Callaway’s production prototype packages in the SuperFlow engine dynamometer cell at Callaway’s Old Lyme Connecticut facility. This testing is performed using the same processes and data correction procedures as used by GM, per SAE specification. Consequently, the values can be compared directly to GM advertised power ratings for stock vehicles.
Can I delete the Callaway badges?
Yes, you can “Option Delete” trim and certain accessories. However, there is no price reduction. Our production and pricing is planned around a certain volume. Callaway cars and trucks are engineered with components that work together; we do not modify the specification for individual vehicles. And badges and identifiers are not supplied separately. This helps defeat counterfeiting and preserves the value of the marque.
Can I keep my own exhaust system?
Callaway mechanical components cannot be substituted in authentic Callaway packages. We can use only Callaway Exhaust Systems. The components are tested, validated and certified in this configuration. Additionally, these components are the only ones that will produce the stated power. Plus, the engine calibration is specifically designed for the complete Callaway powertrain package.
What happens to the stock parts you remove from my car? Can I get them?
Callaway Authorized Dealers prefer not to handle the “take-off parts”. Consequently, Callaway’s prices have been established with the assumption that the take-off parts won’t be returned to the dealer or retail purchaser. Callaway sells these parts to used Corvette parts dealers. If you want some or all of the take-off parts from your car, let your dealer know and prices will be provided.
How does the Callaway Warranty work?
The Callaway Warranty is provided as standard equipment and covers all of the Callaway-installed components and most GM original equipment powertrain components. The term of the Callaway Warranty is 3 years or 36,000 miles, whichever comes first. An optional 5 year/100,000 mile Callaway Powertrain Service Contract is also available.
Which powertrain parts are covered and which are not under the Callaway Limited Warranty and the Callaway Powertrain Service Contract?
Most powertrain parts are covered by either GM or Callaway. Powertrain parts that are not covered by Callaway are listed in the Limited Warranty and Extended Service Contract documents.
Is my GM warranty voided when I buy a Callaway?
No, your GM warranty is not voided. All non-powertrain-related parts of your Callaway are still covered by GM. If your problem is powertrain-related, Callaway works with the GM Dealer to determine the root cause. If the problem was caused by a defective GM component, and the affected components are covered by the GM powertrain warranty, then GM reimburses the dealership. If the problem was caused by a Callaway product defect and the affected components are covered by the Callaway Extended Powertrain Service Contract, then Callaway reimburses the dealership.
Do I have to bring my Callaway back to the Callaway factories for warranty or service?
No. All Callaway maintenance, service or warranty repairs should be performed by your local Authorized Callaway/Chevrolet Dealer.
Do I have to bring my Callaway to an Authorized Callaway Dealer for service or warranty repairs?
No. Authorized Callaway Dealers employ specially trained staff; however, we realize that returning to an Authorized Callaway Dealer may not be possible or practical. Consequently, you may bring your Callaway to any Chevrolet dealer for maintenance or service. Most maintenance and service is performed as per Chevrolet’s prescribed original equipment procedures. However, upon bringing your Callaway to a “non-authorized” dealer, please instruct the Service Writer to contact Callaway Technical Service at 860 434 9002 before any diagnostics, service or repair is performed. Then Callaway will be able to supply specific replacement parts, technical assistance and warranty reimbursement, as appropriate.
Do I get a free loaner or a rental car allowance if I have to leave my Callaway at the dealership?
No. Neither a free loaner vehicle nor rental car allowance is provided by the Callaway 3 Year/36,000 Mile Limited Warranty or by the Callaway 5 Year/100,000 Mile Powertrain Service Contract.
Can I do my own oil changes and other maintenance?
Yes. You are not restricted from performing your own maintenance. However, all Callaway Limited Warranty and Extended Powertrain Service Contract repairs must be performed by GM dealerships. If you perform your own maintenance and a warranty-related issue should arise, you may be asked to provide receipts and other maintenance records. The use of GM-approved oils, fluids, and service parts is required.
If I install headers, modify the supercharger, or re-tune the ECM, will I void the Callaway Limited Warranty or Extended Powertrain Service Contract?
Yes, if you perform any modifications which defeat or tamper with the operation of vehicle emissions systems or install or modify any components or programming that affect Callaway product specifications, the Callaway Limited Warranty and Extended Powertrain Service Contract become null and void.
When does the term of the Callaway Extended Powertrain Service Contract start and end?
The start date of the Powertrain Service Contract is your Callaway’s in-service date: the day you took delivery of your new car or truck. The start mileage is the odometer reading indicated when you took delivery. The Callaway Powertrain Service Contract expires on the same day of the sixtieth month after your in-service date, or your in-service mileage plus 100,000 miles, whichever occurs first.
Is the Callaway Extended Powertrain Service Contract transferrable?
Yes, the Extended Powertrain Service Contract is transferable to subsequent owners by applying to Callaway for assignment within thirty (30) days of change in ownership. Transfer fee, transfer form and complete procedure are available from Callaway upon request. Callaway will recognize the owner of record in the GM vehicle data system as the owner entitled to Service Contract benefits. If the Service Contract has been transferred, the GM owner of record data must match the assignee data on file at Callaway.
