Unlock the true Power

Reviewed By Robert R (Fort Worth, TX) Reviewed for a 2014 GMC Sierra —6/20/2014 4:21 PM

The Diablosport really woke up the 6.2L engine in my Sierra. I used the Diablo Tune (93 Octane Tune). Every aspect of driving my truck has been improved except for fuel economy, but that is my fault I just like getting on it.
