RE: whats the best performance tune for a 2011 gmc sierra 5.
i used to use the 87 octane tune on my silverado 5.3
it made a very noticable improvement and didn't hurt my MPG. i'm trying out the MPG Booster now to see if i gain any better fuel mileage
the Diablo Tune will be the best, performance wise but it requires premium fuel
