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.
So just want to know will this product increase the low end torque and overall power for my 2009 jeep wrangler. I have had several jeeps through the years and currently the low end take off power of this jeep feels like a 4 banger top end is fine but in 6th gear if you start up any kind of grade you need to shift down.

Per the manufacturer: The JET Performance Module for Dodge, Chrysler and Jeep vehicles is a JET exclusive. Dynamic Spectrum Tuning provides power gains across the entire power band-not just at full throttle. Point by point air/fuel ratio, ignition advance and various other tuning points provide performance gains of up to 25 horsepower. Improves throttle response, acceleration and low end torque.
