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 Programmer Reviews

Exactly what I needed

Reviewed By Lester M (Salisbury, NC) Reviewed for a 2003 Chevy Silverado —10/14/2016 3:33 AM

I purchased a different controller at a higher price. It caused the check engine light to come on and it surged when idling. I spent (6) 20 minute unsuccessful attempts to talk to their customer service without any success. I ordered the Hypertech. Everything was programmed in 10 minutes with the Hypertech. I've owned another Hypertech unit for 8-10 years and it still works perfect. I don't know why I didn't get Hypertech first. I love my Hypertech and so does my truck.

Hypertech Speedometer Calibrator Reviews

Worked after trying different tire heights

Reviewed By Matthew E (RENO, NV) Reviewed for a 2016 Dodge Ram —10/25/2016 8:13 AM

So it works great, but required trying different tire heights to get it right. First I compared speeds using my hand held GPS unit and it was off after entering the manufacturer spec of my tire. I learned this is not the height I should use, but rather the height of the tire measured from the ground to top of tire with weight of the vehicle on it. My tire according to the manufacturer measures 33.98", however with the weight of the truck on it, it actually measures just under 33".
