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
