Range Active Fuel Management Device Works Great So Far

Reviewed By Tom S (Collierville, TN) Reviewed for a 2008 GMC Sierra —1/16/2016 7:14 AM

I've had the Range AFMD installed on my 2008 GMC Sierra for about a month now and observed a significant reduction in oil consumption, especially when driving a lot of highway miles. I would recommend this device if you have a similar vehicle where you're experiencing high oil consumption. One drawback is the new SmartRide driving devices the insurance companies are using to get customers up to 40% off their insurance premiums uses the diagnostic port as well.

Hypertech Max Energy Programmer Reviews

Hyper Fast.

Reviewed By Jeffrey F (Schenectady, NY) Reviewed for a 2008 GMC Sierra —8/28/2014 12:54 PM

Fast shipping. Excellent value. Only issue I had was having to update the programmer new out of the box? Otherwise easy install. Using the econ setting so I don't necessarily feel a performance gain but hoping for better fuel mileage. Only programmer I use is Hypertech.
