Great Tuning

Reviewed By Jeff V (Ireton, IA) Reviewed for a 2015 Chevy Silverado —2/27/2018 8:07 AM

The diablo tune on this tuner along with transmission hard shift tune works amazing, with it on Diablo tune I saw a mpg increase of about to 1.6 mpg. I am burning straight E85, now i get my normal fuel economy while burning E85 that only costs me $1.59 vs $2.59 a gallon. The pickup drives much better and stays in a higher gear while driving because it now has a lot more power to pull the hills. Only complaint is having to update the tuner when you get it which should already be done for you IMO
