[6pack]

I had a Jet in a past truck. And same as Pewter, I wouldn't buy it again. I didn't notice any change in performance or mpg.

I've had the pcmforless in for about a month now in the H3. It was worth the money. I can notice a difference in performance (not huge but noticeable) and have noticed about a 1mpg increase over 3 or 4 tank fulls. I did the loaner program and it was painless. All told it was about a two week process. The security relearn happened just the way the instructions said and I didn't need to do it when I got mine back. My change oil message was on while I had the loaner but it went away when I put back in the original. Kelly was the person there I dealt with. She was quick to respond to my many emails. It was a good buying expereince.
