DiabloSport Now Supports 2016 Chevy/GMC 6.0L Trucks

We are excited to announce 2016 Chevy/GMC 6.0L truck coverage for the inTune i2 and Trinity.  We worked with our calibration team to deliver improved horsepower, towing and mileage potential on the 6.0L.  The results speak for themselves.  Our industry leading tuning adds up to 50 HP and 50 LB-FT of torque to the tires!  Making huge horsepower gains is only beneficial if you tune the transmission to get that power to the tires effectively.  We designed our transmission tuning to make the most of the power gains while providing an incredible driving experience.
Tire size/gear ratio calibration, cooling fan control, idle RPM adjustment, shift point/firmness adjustments, and torque management adjustment are just a few of the many features included with this release!  The inTune i2 and Trinity products give you easy to use tuning options paired with high powered calibrations designed to deliver Power You Can Feel from Diablo!  Learn more about this exciting coverage including horsepower levels, dyno chart, and features here.
