+1It would help if the original poster listed the truck and drive train.
Blackbear Performance.
This is the tune you seek. You may not win drag races, but they make your truck a better truck![]()

If you have a Chevy gasser, I second Black bear.
If you have a Chevy diesel 2001 or newer you will need EFI Live tuning.
Blackbear utilizes EFI Live tuning but the last couple of times I tried to get diesel tuning from Justin, he just didn't offer it for Diesels. He may now but if you want a good diesel tune, I'd look up Idaho Rob or I can give you a few others that I've used if you pm me!
