DiabloSport inTune I-1000 Tuner Reviews


It does what I expect and more

Reviewed By Erik R (Anza, CA) Reviewed for a 2009 GMC Sierra —5/16/2015 1:43 PM

Dang. I didn't realize there was a 500 character limit. So I will keep this short and sweet. Power 5 Ease of use 5 Tuneability 4 Instructions on what does what 3 If you don't care about your 0-60 times and yada yada buy this tuner. Oh! Do NOT adjust your tune if you have smog/state inspection coming up. They don't tell you that if you adjust parameters you will fail. It took about a week for my truck to go through the "GM cycle". Great buy, autoanything rocks

Nice tuner.

Reviewed By Cody H (SODDY DAISY, TN) Reviewed for a 2004 GMC Sierra —10/9/2014 8:48 PM

Bought this tuner to go along with my full exhaust and intake. Made a very noticeable difference in power and the way the truck shifts. No mpg improvement that I've noticed, but not why I bought it. Would definitely recommend on GM trucks. Also allowing for custom tune is nice as well.

Diablo Predator vs Hypertech Max Energy...Diablo wins!

Reviewed By Bryan H (Clinton, IA) Reviewed for a 2007 GMC Sierra —5/13/2011 8:57 AM

The price from Auto Anything was the best I could find on my Predator. After using Hypertech Max Energy (also bought at AA) the Predator does much more, you can actually adjust your tune to get it dailed in close to perfect. When I bought mine, the ad stated that the Predator could Eliminate PO codes, as well as just scan as clear. That was not the case. That feature was removed years ago. After calling AA they have removed that from the add and the guys at Diablo did me right by sending me a custom tune that does eliminate the codes. These guys are awesome. With my new custom Diablo tune, this truck rocks!
