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.

Not sure, but I'm happy

Reviewed By Tony C (Carolina, PR) Reviewed for a 2011 Jeep Grand Cherokee —2/26/2015 1:38 PM

I hated the pick up on my 2011 Jeep Grand Cherokee Overland, and can attest that after I plugged in the Tuner I definitely felt much more "pep" when I step on the gas. However, my MPG has gone to crap. I think on highway I do get better mileage now, but in city I get worse, and I drive mostly in the city. Someone who puts mostly highway miles should see an improvement. Either way, it made me much happier to drive my car, and that is worth the 300 bucks to me.
