This thing unleashed the beast

Reviewed By Dan D (PLAINVILLE, CT) Reviewed for a 2009 Jeep Grand Cherokee —7/25/2016 8:18 PM

Huge difference in my 4.7 Grand cherokee...woke it up! this thing runs and gained 2 mpg in fuel economy. Only reason I rated ease of installation low was because I haD TO WASTE 15 mins updating it on my pc. for the amount of money I paid it should be pre updated. and its a bit pricey.

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.

It works

Reviewed By Ray Y (Colorado Springs, CO) Reviewed for a 2005 Jeep Wrangler —9/13/2017 8:30 PM

I installed the tuner on my '05 Jeep Wrangler using the mileage option. I can't tell any difference in performance, but I did gain 3 MPG. I started at 15 MPG and now I get 18 MPG. That is a 20% improvement.
