Easy to use and update- gain of 3MPG
A 5.7L HEMI is a gas guzzler by definition. That being said, I would od an add on here, another there, when I could get products on sale at AutoAnything. So, with this, and the K&N cold air system, throttle body spacer, Accel super coils, plasma plugs, and Magnaflow exhaust, I effectively went from an average of 13.5 to 19.5 MPG- in the mountains, mind you. The Superchips programmer worked in tandem with these, to give me the last three MPG average upgrade.
look ma its a jeep
I think its mostly for jeep stuff.......at least the instruction book is mostly about jeeps and the programming is mostly on a loop...it never actually informs you if what you just entered was accepted or correct and you have no clue if you completed your re programming.......they tried to put to many prompts and commands on one multipurpose e-prom......and to do that they had to leave a lot of the simple commands off the chip........and the command buttons are to small, not good guys.
