DiabloSport inTune i2 Tuner Reviews


So far so good.

Reviewed By Bruce K (LYNDON STATION, WI) Reviewed for a 2013 Chevy Silverado —5/22/2017 8:28 PM

I just dropped the 87 Octane tune with firm shifts and turned off AFM. The truck shifts smoother and it seems to have helped a lot with the driveline clunk when getting back on the gas after slowing down. A custom tune is in the future.
