Range Active Fuel Management Disable Device Reviews

Fouled plug

Reviewed By James W (Elizabeth City, NC) Reviewed for a 2008 GMC Sierra —11/8/2017 4:47 AM

190,000 miles and a plug fouls. My mechanic narrowed the problem to the fuel management system. Installed the Range device and problems solved. Can't tell any difference in fuel milage. ??

Better then pods

Reviewed By Sam O (KNOXVILLE, TN) Reviewed for a 2008 GMC Sierra —9/13/2017 5:13 PM

Up to 9 gauges at once and easy to use. Best part is you can check your check engine lights and clear the codes. And has a good maintenance reminder on all a wide variety of maintenance for your truck. The only thing I am not sure about is unplugging and replugging it in if it saves your data.
