DiabloSport inTune I-1000 Tuner Reviews


Suuuuuper easy to use

Reviewed By Jon L (BEAVER DAM, WI) Reviewed for a 2014 GMC Sierra —12/5/2014 8:11 PM

Easy as can be right out of the box. I even used a Mac and had no issues updating the device. Simply plug it into your vehicle after updating, pick your desired tune, let it do its thing, and done. Installing tune took less than 10 mins total. Capped off with the Diablo Sport OBDII cover. I plan to have a custom tune written by DiabLew once I'm done installing different exhaust components to maximize everything's potential.

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!
