"Had already installed Airaid throttle body spacer, free flow air intake, Acel Super Coil and 8mm plug wires along with Bosch Platium Plus4 plugs which had improved preformance and gas mileage in my 97 Jeep Wrangler SE with a underpowerd, overworked 2.5 4 cylinder. In less than 15 minutes that it took to install the JetPreformance Module #90017, which is the basic chip, I could tell when I turned the switch we had hit paydirt, fired instantly, ran smoother. TEST DRIVE Got in, put it in reverse and it backed itself out of the drive, put it in drive and could tell with the first gear shift, mission accomplished. Now the Jeep drives with less effort, shifts with less strain, accellerates quicker and gets about 2 mpg better milage over what the prior upgrades had accomplished. I almost wished now that I had stepped up to the stage II chip and some where down the road may do that." —Jeffrey O from Knoxville, TN bought a Jet Performance Module for a 1997 Jeep Wrangler, 2.5L 4-cyl..
