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

Better than Bully Dog

Reviewed By Jonathan W (Killeen, TX) Reviewed for a 2015 Chevy Silverado —6/21/2016 4:47 AM

I had bully dog before this one and it took me and my truck through the ringers. This product I should have stuck with since my first use in 2004. I love this product and will recommend to anyone.

Worked well!

Reviewed By Shane P (MOORE, OK) Reviewed for a 2015 Chevy Silverado —6/10/2016 4:39 PM

Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.
