Has anybody had any luck with a used Hypertech PP3 that the previous owner returned to the original settings.

 

I have one I got used.. no probs with it..
I use it for top speed limiter removal, fan temp lowering, change shift points, etc.. and soon to compensate for rear gear change..
Never tried the 'power programming' since from what I read it does little or nothing..

 

Yep... I've bought two HPP used and both were fine. You just have to have a little faith in the buyer that he/she will in fact take the programming out of the car before they sell it to you.

 

I bought a hpp3 couple months ago from 2zpoint i think his name is. Worked fine for me. I plan on selling mine in a few weeks or so (going with a custom tune fromm madwolf or pcm4less)
