Typical turnaround time is 2-4 days from receiving order, processing, to getting them shipped. (Certain circumstances will create a delay, such has holidays & weekends.) However, some items may possibly be on back order. For the type of products we offer and for how fast the availability turnaround time is, we are unable to keep a stock quantity on the website. Although you can purchase items, some may be out of stock.

If that is the case, we will email you to let you know that your item is on back order and we will ask how you’d like to proceed with the order.

JET has a 30 day return policy. All returns are subject to being charged a restocking fee of 25%, at JETs discretion. Electrical parts that have been opened and/or installed are non-refundable. Proof Of Purchase Must Be Provided.

PLEASE NOTE: FREE Shipping costs will be deducted from your Returned Items.

This is NOT the same as warranty. Things covered by warranty are for manufacturer defect, meaning you opened the package and the product didn’t work by some fault of ours. Return means you bought it and no longer want it and it must be UNOPENED. Items purchased more than 30 days ago, are NOT available for return.

When you have received an RMA number to send back in your product you must pay for shipping prior to sending it back. Any returns sent COD (Collect on Delivery) will be refused.

All shipping charges & duties are the responsibility of the buyer for any returns. JET will not be responsible for any shipping or duties charges for these transactions.

The quick answer is no. For credit card processing purposes and courier settings we are unable to send to a PO box. We recommend that you use a valid street address otherwise your order may be held up in processing until we receive a valid address or it may be cancelled.

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 self-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.” For more information see SEMA’s website at www.sema.org.

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-234-6 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 49 states.

If the item you purchase is not covered by a C.A.R.B. Executive Order Number & you live in California, your purchase will be refunded and the order will be cancelled.

Our Mass Air Flow Sensors will work with most cold air intake systems. However, they aren’t calibrated for wide open cold air intake systems.

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 and vehicle weight. 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. See the Dyno Sheets and/or Horsepower Gains sections for information on your particular vehicle.

Stage 1-For stock or mildly modified vehicles. Fuel and timing curves modified for optimal performance and mileage using midgrade fuel (89 octane or better recommended). Good for daily driving, towing and street performance. Improves horsepower, torque, overall acceleration and throttle response. No other modifications to vehicle are required, but the Stage 1 programming will work with most aftermarket upgrades without using premium fuel.

Stage 2-Designed for the performance enthusiast, the Stage 2 features more aggressive programming to make the most horsepower and torque available. The Stage 2 programming requires use of 91 octane fuel to optimize the advanced timing curves, a 180 degree thermostat to provide a denser air/fuel mixture and a free flow exhaust system to reduce back-pressure. The stage 2 will also enhance the performance of aftermarket intake systems, mass air sensors, TBI spacers, etc.

* Only applies to GM & Dodge

The factory programming is designed for the average driver and is designed 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 lower quality gasoline and poorly maintain their vehicles. For a real high performance person who carefully maintains their vehicle midgrade or premium is all they ever use. JET Performance programming optimizes 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 a well maintained vehicle using better than average fuel.

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.

Custom Programs are available if you have installed aftermarket intake manifolds, camshafts, large mass air-flow sensors, nitrous oxide systems, or any type of supercharger or turbo system. 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, cold air intake systems, cat back systems and TBI spacers 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 800-535-1161 or email at [email protected].

JET Performance tuning replaces stock computer tuning inside the vehicle computer to give maximum power and torque. The tuning can be delivered in the form of a chip that replaces the stock computer chip, a chip that piggy-backs the stock computer chip, a chip that plugs into the back of the stock computer, or a module that intercepts and modifies the signals from the stock computer with JET Performance Power Tuning. The type of computer in your vehicle dictates the type of device needed. The tuning information is stored in the computer chip which controls all of the engine’s characteristics like air/fuel ratio, spark advance, shift firmness, shift points, top speed, rev limit, and axle ratio. Sensors monitor many engine and transmission parameters like RPM, manifold air pressure, mass air flow, coolant temperature, intake air temperature and many more. These sensors send this information to the computer. The computer uses this information delivered from the sensors along with the information stored on the chip to deliver the optimum air/fuel ratio, spark timing, shift firmness, etc. for this set of operating conditions at that instant in time. JET Performance can tune a vehicle for the conditions by using a dynamometer to measure horsepower output while altering the information stored on the chip. This is how JET Performance maximizes your vehicle’s power output!

JET Performance Power Tuning does not alter your vehicles calibrations in any way that would hurt fuel economy. Fuel economy will remain virtually the same or may even improve (depending upon specific driving patterns) unless the vehicle is driven in a spirited manner (lead foot). For trucks that tow, JET Performance’s Power Tuning is generally closer to the better fuel economy than the stock tuning. So in addition to power gains, a vehicle that tows with JET Performance installed will often exhibit better mileage than one with stock tuning.

JET Performance Programmers include the option to remove the speed limiter and in most cases modify the rev limiter, but JET modules will not remove the limiters. Speed limiters are based on the speed rating of the OEM tires and changing these limits are done solely at your own risk! In some cases the limiters can be removed with custom programming, contact JET with your vehicle specifications to be sure.
