Just installed the mpg boost tune a few min ago. Will test on my way to chicago.

Mpg tune was a joke. Went down 2mpg driving defensively highway using cruise. Installed 93 perf. Tune and mileage went back to stock but with more kick. Looking forward to more info and tests being posted.

Maybe so. I was running mid octane like the gc manual says to when I put the mpg tune in. Same gas I was running before the tune. Started at 18 pre, and got 15.7 post tune at around 72mph for 3 hours.
I put 93 in for the 93 tune and got 17.5 at about 75-80mph for 3 hours. Mpg went up at that speed.

Highway, right? You're not averaging that with city driving in the mix are you?

Cool. Thats what I get with 93, and a lot more kick.
