Got the first tune for my 8 speed 6.2 Yukon XLD. Guys, your work is fantastic and no BS. Tip in acceleration and shifts all the way to 6 grand is money. Transmission changes are good but hoping you can further refine for me, if possible. I just sent the new datalog to you and I know you'll do your best. Big props, Black Bear.
