September 3, 2004i know they work for the ford trucks., friend had one, they are a good company, I would trust them to supplying a nice product for your jeep too
July 2, 2005HAVE INSTALLED IN MY 96 F-150/5.0,H.O.,WORKS GOOD ON CHEAP FUEL.THINKING OF TRYING ON MY 04 TJ "X" 4.0L/H.O.
July 3, 2005I have one for the Wrangler, I defintely noticed a difference even with the other mods. Just have to run 89 octane. I also tried the 92 octane program and it really showed more improvement. I just dont want to pay for primo gas all the time.
I would recomend it for the 4.0 though!!
July 3, 2005No personal experience on my YJ, but on the Camaro it took it from running 13.4's to 13.0's. A pretty decent improvement for about 15 minutes of work without even getting greasy. If you can afford it, I think everyone should do the reprogramming. It really does make a difference.
July 5, 2005I need one, at the very least I need to recalibrate for the tires. Anyone know of custom tune shops for the 4.0?
