DiabloSport Trinity T-1000 Programmer Reviews


Overpriced but looks great, and gives a bit of power

Reviewed By Ty M (WEATHERFORD, TX) —7/12/2015 6:21 AM

Ordered it while my car was in the shop for my Dodge Challenger r/t, and was excited to install. Fast forward another month and I finally install it. The install was a bit confusing but simple as well. The tunes themselves are confusing because there were many and I didn't know what to choose, chose a sport one and finished the install. Driving it I did see a better peddle response for sure, it took off noticeable faster. Though I didn't feel much power gain overall, but it is there.
