Will JET Performance tuning void my warranty?
No. Federal law prohibits a dealer from voiding your warranty just because you are using aftermarket speed equipment, with only two exceptions: the warranty can be voided if the aftermarket part causes damage or adversely affects the emissions or the emissions system. In recent documents produced by the SEMA (Specialty Equipment Market Association), a trade association-representing specialty automotive parts manufacturers, and the following quotes have been extracted:

"The vehicle manufacturer is not allowed to void the vehicle warranty just because aftermarket equipment is installed on the vehicle. This protection for consumers is the result of a parts self-certification program developed by the Environmental Protection Agency (EPA) and the Specialty Equipment Market Association (SEMA).

"Under the program, if a parts maker completes the EPA process of s! elf-certifying its parts, the vehicle manufacturer cannot void the warranty even if the certified part has failed and is directly responsible for the warranty claim. In cases where such a failed aftermarket part is responsible for a warranty claim, the manufacturer must arrange a settlement with the part manufacturer, but the new vehicle warrant is not void under the law.

"If the failure to honor a claim involves the new-vehicle warranty, and it appears that the manufacturer is improperly denying a claim, the incident should be reported to the Federal Trade Commission (FTC). The FTC is responsible for monitoring compliance with the warranty law; the agency's telephone number is 202/326-3128."

Are JET Performance Chips emissions legal?
Yes. All JET Performance Chips and most Performance Modules are 50 state emissions legal. They do not change the emissions at all from the stock tuning chip for any Federal or local emissions test. C.A.R.B. (California Air Resources Board) has issued Executive Order numbers D-234 through D-234-5 covering all JET Performance Power Chips, making JET Performance chips the most complete line of high-performance chips that can legally be sold, installed, and driven in the state of California. Because of C.A.R.B.'s very rigid rules concerning exhaust emissions, the Environmental Protection Agency ( E.P.A. ) accepts C.A.R.B. approval as evidence that an aftermarket part is clean and suitable for use in all other states.

What performance increase can I expect from JET Performance Tuning?
At JET Performance, we carefully dyno and track test every product we sell...in fact, it is these tests that tell us when we have the best possible tuning. Of course, the power gains are different for each engine family. However, power gains range from about 10 Horsepower to over 50 H.P. on supercharged or turbocharged engines, resulting in a 2 to 7 car length improvements in the quarter mile. Zero to 60 M.P.H. improvements are typically about 1/2 second.

What's the difference between Stage 1 and Stage 2 Power Tuning?
Stage 1 Tuning is designed for the stock engine with very little modification. It requires the use of 89 or higher octane fuel for best results. The Stage 1 tuning will work in conjunction with other modifications to increase performance (intake upgrades, exhaust upgrades, etc.)

Stage 2 Tuning is designed for the performance enthusiast. Premium fuel is required in order to extract the maximum benefit from the new tuning. Other modifications including, less restrictive exhaust, modified intake, and 180 degree thermostat are recommended prior to using the Stage 2.

If JET Performance Power Tuning is so great, why didn't the factories do it that way?
The factory program is designed for the average driver and is set to take a wide variety of operating conditions and driving styles into consideration. Consequently, stock calibrations aren't set to provide maximum power because they have to accommodate drivers who may use poor quality gasoline. For a real hi-performance person, premium is all they put in their vehicle. At JET Performance, we optimize the spark and fuel curves over the entire RPM band from just off idle right up to the redline for maximum power and performance from the best gasoline.

Will Power Tuning hurt my engine in any way?
No. Best power is always made when air/fuel ratio and the spark tuning has been optimized for maximum power, meaning maximum "push" on the piston during each power stroke. Damage occurs if the air/fuel mixture is too lean, meaning that there is not enough fuel for the amount of air in the cylinder. This results in excess super heated air, which can cause burning of valves and pistons and will also induce detonation (which can break pistons, etc.) Relative to spark timing, too much "advance" will cause detonation, which reduces power and can also damage parts exactly as a lean mixture does. When you finish installing JET Performance on your vehicle, your engine will run at maximum efficiency yet safely distanced from possible damage due to leanness or excessive spark advance.

What happens if I have or plan to install other aftermarket equipment?
Custom Programs are available if you have installed headers, intake manifolds, camshafts, large mass air-flow sensors, nitrous oxide systems, or any type supercharger. You absolutely need JET Performance Custom Programs with these modifications for both tremendous power gains over stock tuning, as well as to eliminate the probability of lean air/fuel ratios and excessive spark advance which are death to modified engines. You do not need a Custom Program for engines that are stock or mildly modified. For example, high-flow air filters, cat back systems, or ram air scoops work perfectly with our Stage 1 or Stage 2 Power Tuning. If you suspect that your modifications would benefit from custom JET Performance tuning, call our customer service department at 800-526 9952 or email at i5auto@msn.com .

Does JET Performance remove the speed and rev limiters?
It depends on the specific vehicle. On most chips, we eliminate the top speed limiter. The rev limiter is raised when possible and is completely dependent on the application. The SCU 2000, available for 1996-2000 GM cars and trucks (see catalog for specific vehicles) allows the user to remove the top speed limit. It will also allow the user to calibrate the speedometer for any changes made in tire size and/or gear ratio.
