If you followed the Superchips directions, they should fix it.

You might find a dealer who will fix it under warranty - but you will have to go through the hassle of towing it there and telling them that "it just wouldn't start". Then waiting for a day or so for them to diagnose the problem and reflash or replace your PCM.
I scrambled my PCM with LS1Edit and took it to an LS1 performance shop (as BigTex suggested) for a re-flash back to stock - no muss, no fuss, no towing.

 

Do not bother with negotiating with superchimps. One guy I talked to was fairly cool, but the rest were complete ********. I would NEVER recommend any of their shoddy, half *** products to ANYONE.
I got stuck with their tune on my truck, and did some quick learning on Edit to get my stock timing tables back right beofre I put the blower on.
They will pin the blame on the user, so they don't have to re-imburse you for anything.

Put it this way, I still have a superchimps box sitting right here. I never sent it in to have it re flashed, because I have no use for it, and would never sell it to anyone else, cause it is so shitty. Sam

Good luck with it
