Hey everyone new guy here i have had the software for about a year just learning the basics and getting a feel for how everything works and i have finally gotten the courage to ask for some help. I have a 2011 silverado that was custom tuned by diablo it was so so when i first got it but know it just flatout sucks prob due to lack of changes that were done? Basicly im looking for some decent mpg with some performace and a good faster shifting trans . So if any pros wish to share a few secrets or pointers i would greatly apreciate it however anyones tips or pointers would be helpful thx
