Best Tuner on the Market

Reviewed By Steven Y (Haleiwa, HI) Reviewed for a 2015 GMC Sierra —6/7/2016 1:52 PM

I owned a I-1000 and it was ok. This newer on is faster and you don't have to press extremely hard for the buttons to respond.Also going back to stock is way faster than the first series.

DiabloSport Trinity T-1000 Programmer Reviews


Exactly what I was looking for.

Reviewed By Donald S (TECUMSEH, OK) Reviewed for a 2005 GMC Sierra —2/13/2016 7:22 AM

Tuner has very good tunes an abLe to upload custom tunes via download or micro chip. Can't beat this tuner the Trinity customer service SUCKS!! I emailed them asking how to make the tuner to power down once the ignition is turned off after 4 days I got a response from them, all they said is to unplug it from the ECM port. When i mentioned wanted to use the gagues feature while driving the CS Rep came back with "sent it back where u bought it an get a refund then". That isn't cool at all.

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!
