Ok, I'm new to this for the most part. What do I want to consider doing when I send my data log in? I've got a 2012 Denali XL. Exhaust and intake only.
Tune wise what is good? Sport mode in with the tow mode button sounds nice. Losing some torque management, firmer shifts. I run 93 in the truck.
What else do I need to consider?
