Jet Chip Stage II

Has anybody made this modification to their jeep. truckperformance.com claims gains of 10-15HP/20 ft lbs Torque, I have to say that I have no way to test against this, but I cant even tell that the stupid thing is even present in my jeep. Im thinking about selling it on ebay, I was just wondering if somebody out there made this mod and thinks its imroved thier jeeps performance.


98' TJ 4.0L 6" lift, FIPK, K&N Exhaust, TB Spacer, Stage 2 Jet Chip, cooling mods, nerf bars, double tube front bumper, 4 auxillary lights, HID headlights, Hi-lift jack, 35" tires, etc.

These numbers are usually at the Fly Wheel numbers...and you can pretty much take 1/2 of those numbers and thats what your truley seeing/feeling at the wheels. 5-7RWHP and 8-11lb/ft of torque.

There is no way that you would normally feel a 5HP improvement. Now where different tuning comes into play is if you improve the intake/exhaust (breathing) of the motor, then you can use the more aggressive fuel curves to your advantage.

Say if you had a header/larger TB/catback system/CAI...and installed this tuning...you would probably notice a small improvement in overall performance...

personally i would do as many mods to the engine as possible before i bought a chip, and then called up JET or Hypertech or whoever and tell them the mods that you've made so they can custom program a chip for your rig.

I think you can send it back and have them reprogram it to work with the mods you have.
