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

Hypertech Max Energy 2.0 Programmer Reviews


Great product and very helpful tech support

Reviewed By Joe T (ERIE, PA) Reviewed for a 2016 Chevy Tahoe —5/9/2017 5:15 AM

I was a bit nervous after reading the instructions and warnings about making sure that all devices that use power from the car battery are turned off and/or fuses for them are pulled so I called the Hypertech tech support guys to make sure I wouldn't screw up. The instructions were very clear and the programmer worked perfectly. I was able to turn off the AFM system so my Tahoe no longer goes into V4 mode. I get better gas mileage & more horse power.
