What is the best chip to buy? thanks.

 

H For the H3; there really is no "chip" worth buying. There is a Jet Power Control Module, but I have not heard the true results of same for the 3. I had one on my old GMC and it worked pretty good, think it gos for appx. $232.00.

THE BEST DEAL is a PCM tune from PCMforless. It is easy with their loaner program, MOST EXCELLENT Bang for the Buck, and costs less than a Jet module. Everybody in this forum that has had it done gives positive feedback. Cost with loaner and mailing charges after the loaner core refund is appx. $180.00.
