I'm having thoughts on tuning the hoe based on how much I liked the tune in my Sierra. I know the AutoCal is the big thing these days but I missed all the hype because I wasn't keeping up with GM tuning while I had the Jeep. The website says the tune includes 4 tune files. What I'm thinking is stock (just because), regular tune (86 octane here) for when I'm feeling cheap, and premium tune (90 octane here) for when I'm not.
What did everyone else go with?
