Range Active Fuel Management Disable Device Reviews

Range AFM Disabler - Wish I had purchased this earlier

Reviewed By Jerard D (Youngsville, LA) Reviewed for a 2008 GMC Sierra —2/10/2015 10:58 AM

This is a great little device. It does exactly what it is supposed to do. My 2008 5.3L Sierra 4x4 has been using about 1qt of oil every 1000 miles since about 45,000 miles. The truck now has about 73,000 miles. I've been adding Rislone engine treatment with each oil change ever since discovering the oil issue to help prevent the control rings from sticking due to the oil burnoff. Well, I can tell you that I've driven about 600 miles since plugging in the Range device and have not lost one drop of oil yet. And as an added bonus, I find the transmission downshifts a whole lot smoother. There is also no more V-4 to V-8 power lag(instant power) and the fuel mileage has not really changed. The driving experience has been greatly improved in my opinion, feel like I have a new truck again. I'm waiting for summer blend gas to hit the stations to see what kind of mileage I'll get.

Does what it says

Reviewed By Taylor M (MESA, AZ) Reviewed for a 2014 GMC Sierra —1/26/2015 9:06 PM

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!

Scan Gauge

Reviewed By william s (Fairbury, IL) —1/15/2015 10:14 AM

The scan gauge does everything is said it would. Bought to monitor water and oil temps but watching the MPGs is really interesting and taught me some new driving habits. I did have one problem setting it up and customer service was fantastic.
