I know so many have said this but I want say this if you have been a bit on the fence about doing a Black Bear Tune don't wait do it ASAP. I was on the fence for 200 000 miles and started to have issues with my 07 Z71 and got the tune in hopes it would make it better, and it did! If not just for the sheer performance boost do it to disable the Active Fuel Management system and other GM crap because in the long run that system will screw you motor up, I know. My BBT fix that and I can see me putting another 200 000 miles on the truck.
Thank you Black Bear for awesome service and great product...
