I have a 2010 gmc crew Z71 with 3.08s and I actually like them. My motor has plenty of balls to haul the truck around without having to compensate for power with gearing. Its cruises at 70 and will govern out in 3rd gear. Its a six speed, id like to see what it'll do with a custom tune.

Ps. The 6 speed is a great trans, I like the gearing and overall feel of it.
