http://en.rschip.com/and for our liberties specifically:
http://en.rschip.com/chiptuning/jeep/li ... -i-v6-12v/It really isn't specific to any vehicle but their algorithm/calibration must be pretty good. I saw some dyno results on another forum and people were getting pretty good results on even naturally aspirated engines. Nothing insane but reasonable for the cost. My wife got it for a steal compared to the prices now though. I almost had a heart attack when I saw the price on their site. We aren't people of money so I was glad she didn't pay what they are wanting for it now - she must've got a christmas special.
It's been like 5 days since I installed it and I can still notice the difference. It's all in the throttle response and shifting. That may be all it did but gosh do I love this little device for it. My everyday morning commute is a couple minutes quicker, haha, and after a couple days I tried to stop flooring it constantly but I can still feel the difference.
I had a random airbag dash light come on one day which alarmed me but it did go away the next time I started her back up. I don't think it was the chip itself though... I think I am starting to get some electrical irregularities on cold mornings. I wouldn't pay what they want for it right now but it is pretty dang cool otherwise.
I just feel like the Liberty isn't lugging around as much. I up-sized my tires to 245/70/16's back in late summer and lost a crap ton of power immediately. This little device brought it all back and then some. Or at least it
feels like it... and I was skeptical as hell before I installed it.
