DiabloSport Trinity T-1000 Programmer Reviews


great buy

Reviewed By Eric H (Shorewood, IL) Reviewed for a 2000 GMC Sierra —9/6/2014 1:42 PM

bumped my the gas millage from 10-14 on my 6.0L 2500 gmc. Good throttle response and shifts much smoother when casual driving. Aggressive shifts when you're on it. 0-60 went down 2 seconds.

I had a hard time getting the programmer to match my 2000 GMC. I called tech support and they walked me through their website but that did not work. They said the usb cable was probably bad but that was not the case. After experimenting with the website it finally adjusted to my truck after several hours.

Bully dog woke my sierra up

Reviewed By travis w (joelton, TN) Reviewed for a 2000 GMC Sierra —9/9/2013 8:42 PM

Very nice product and seems to really have helped my truck getting up to speed and staying at speed. It also shows info like trans temp and other usefull information. The only downfall to the bully dog for gas is that it cannot change tunes on the fly like the one for the diesel. I'm not sure it helped my mpgs any but has made my truck a lot more enjoyable to drive.
