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

Great device!

Reviewed By Evan S (SANTA CLARITA, CA) Reviewed for a 2004 Nissan Titan —1/11/2018 10:20 PM

Without changing the rpm limiters, the device changed my cruising rpm to around 900. I took my rev limiter off, and now I go all the way up to the red line when flooring it. I have seen my gas mileage go up. Before, I was averaging around 10.8 with hills, and around 11.2 on flat. Now, I am up to around 11 with hills, but 15 on flat. Its a great device and I would recommend it.
