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

great tuner bought it for my 99 silverado, had put headers on no cats, cold air intake and throttle body spacer, and dynomax exhaust, tried both the 87 octane tune and diablo tune, didn't work the best but then was able to have a tune customized for my truck, really brought my truck alive, never downshifts up a hill 0-60 no problem, all around runs stronger. a custom tune might run 100 bucks or so but tons of things you can play with and adjust on predator. great tuner and is well worth the money.
