DiabloSport inTune i2 Tuner Reviews

Like a whole new truck (2010 Silverado)

Reviewed By William W (West Seneca, NY) Reviewed for a 2010 Chevy Silverado —9/13/2017 7:31 AM

I purchased the tuner to disable the AFM/DoD function that bumps the engine down to 4 cylinder operation. I found that the older my vehicle got, the more lag it would have off the light. This tuner changed it all. I started running a 87 octane tune and already noticed a huge difference in driveability, throttle response, and shifting. It was like a whole new truck. Now running 93 octane tune, the difference is amazing.

DiabloSport Predator P2 Tuner Reviews

awesome product when used with a custom tune

Reviewed By nathan w (Valparaiso, NE) Reviewed for a 1999 Chevy Silverado —4/6/2012 6:31 PM

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.
