2008 GMC Sierra 2500HD Tuner

[klfutrelle]

Hey, I was wondering what is the best tuner or chip to buy for a 2008 GMC Sierra 2500HD with the 6.0?

From what I've learned here, chips are out & Blackbear Performance is in. They have a whole section here to read up on.

I will check them out. Thank you.

^{I originally bought a Hypertech for my 2500 HD 6.0 Gas. It helped with performance but was limited with trans settings. I sold it and got a custom tune at Nelson in San Antonio. Very happy with it and it wasnt much more than the programmer.}
