DiabloSport Trinity T-1000 Programmer Reviews


Thrilled with my Trinity

Reviewed By William S (Dallas, TX) Reviewed for a 2013 Jeep Grand Cherokee —1/22/2016 7:16 AM

I would definitely recommend this tuner/programmer to any car enthusiast that is looking to improve performance in their car. I will say that the canned tunes (the ones that are preloaded on the Trinity) did improve my car (Jeep SRT), but nothing like a custom tune that you can get from someone who knows what they are doing or one you can get when dynoing your car. The interface and software was really easy to use as well as the logging for the custom tuner.

DiabloSport inTune i3 Tuner Reviews


Awesome Results!

Reviewed By John C (OOLOGAH, OK) Reviewed for a 2001 Chevy Suburban —12/2/2017 12:45 PM

2001 Suburban 5.3L which was very anemic before I bought the I3 tuner. Was skeptical with the Plain Vanilla appearance, and lack of full display, but it is not lacking in the Performance Department. I first used the Default 87 octane setting. I pull a 26 ft Warrior Toy Hauler with a Honda GL1800 Goldwing in the back, that bike adds 900+ lbs to the load. The Suburban is being asked to pull more than tongue weight rating, doing a super job and added 3+ MPG while towing.
