I am interested in what experiences you guys have had with performance PCM's and power programmers.

 

the power programer form hypertech is only worth it in my opinion if you just want to use it to re-calibrate your speedo for different size tires or rear end gear. I never really felt a difference in power with the power programming installed, so if you are looking for a big power jolt, dont get the hypertech. especially if you plan on doing future mods like heads and cam. I have been seeing a diablo tuner that seems a little better in the fact that you can download custom programs from the net.

That coming from a guy who's '99 SS is now "broken"
