Diablo for 2013 Silverado

Reviewed By Wayne G (RAY, MI) Reviewed for a 2016 Chevy Express —12/10/2016 4:47 AM

Purchased this in hopes to improve mileage during my DD and to add hp and TQ for when I tow my trailer. You certainly can feel a difference. (I do have a K&N air intake and an MBRP cat back. I look forward to using the tuner with the trailer. I never had one before, It seems light but that's good for hanging on the windshield. Easy installation and decent size screen. I am still getting used to it but the gauge option. Will try Diablo forums.

Motorhome/ Chev Chassis gas 6.0 Installatiion

Reviewed By Robert R (Milton, FL) Reviewed for a 2008 Chevy Express —5/1/2013 3:46 AM

As you can imagine getting any type of improvement in power or gas mileage from this type of a vehicle would be a huge benefit. The aerodynamics are just not there for streamlining this type vehicle. Therefore one has to hope that any improvement with this vehicles performance could come from an aftermarket device. I have good news to report on the power provided by the Bully Dogs retuning of the 6.0 gas engine, acceleration through the power curve is excellent, gas mileage no improvement
