I got my PCM back after sending it to be re-programmed and now it won't rev. over 3500rpms. My sig. has all my mods, and I've got a T56 trans. Anybody have any ideas on how this could be? I've already sent it back to be re-programmed again. Damm this sucks

 

I know theres LS1 edit guys out there who have some kind of an idea... Right.
