JET Performance

Does anyone have experience with the jet performance chip?

Not personally, but from what I have heard the computer eventually learns to adapt to it and you have to do a PCM reset periodically. Better off with a programmer.

Don't!! waste your money on jet crap.... Jet chips are not vehicle specific tunes or anything.... they just trick the PCM into thinking the vehicle is running lean.... thus it compensates and makes the vehicle run rich and dump in more fuel..... this is a stupid way to gain power (if you even gain any) when there are custom tunes available..... B&G performance offers custom tunes for the liberty which actually change PCM programming Hypertech has also recently released a programmer for 2004 and up liberty's .... bottom line ive had a jet Chip in the past installed on my old S10 and it was crap.....
