Great tuner. Love the screen, and the fact it's touch. Diablo still working on tweaks for my 2018 Silverado 5.3 but satisfied with the tune loaded.

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.
