Performance tuning is more difficult vehicles were the factory computer does not have a chip that can be easily replaced. To solve the problem JET developed a plug in module that attaches to the vehicle computer externally that can add up to 30 horsepower. The JET Module optimizes the ignition spark advance, air to fuel ratios and transmission shifting for the ultimate in power and mileage gains.
snappier off line definite power increase. However the fuel milage did not seem to change as I'd hoped for if any I would only reccommend this to someone who is only looking for a power increase, and not fuel milage.
Thanks for asking. Most performance chips or modules are calibrated for a specific set of modifications or a stock vehicle. This particular Jet Performance module is calibrated for a stock vehicle.
