Just bought a 04 2500 Chevy with a 6.0. What comp. Chip is best for towing, economy and performance?

theirs a guy in upstate NY that programs the pcm,s for what ever your needs are..had a friend with a 1/2 ton that picked up like 2 seconds in the 1/4 mile..i dont know who he was but i know it was in NY somewhere..

Find someone with, or purchase efi live and get a tune from Blackbear performance. I do all my own diesel tuning but order gas tunes from them.

new era performance in rochester ny. they do incredible work with LS based chevy stuff

don't bother with a hypertech or any other hand held tuner, get a custom tune with a laptop
