I've never heard of them, but as far as custom programming goes I highly recommend pcmforless.com.

They are a well known tuning company in the b-body and f-body crowds and do great work.

I have one of their custom tunes on my 96 SS and I gained over 30 hp from factory power levels.

A popular but cheap performance upgrade over at gm-trucks.com. I was seriously considering one of these if I kept my 2004 Sierra. Drive by wire really let GM kill the performance of that truck off the line.
