Range Active Fuel Management Disable Device Reviews


Good So Far

Reviewed By Michael S (MONTEVALLO, AL) Reviewed for a 2009 GMC Sierra —4/17/2015 9:53 AM

I've noticed smoother shifting with this device,as well as full time V-8 power when climbing hills or passing.I haven't noticed any mileage changes,and cannot comment on the oil consumption issue until I've driven the truck longer(oil consumption is an issue related to the active fuel management system).I have recommended this device to other truck owners.

seems to do the job

Reviewed By jeff l (POTTSTOWN, PA) Reviewed for a 2003 GMC Envoy —8/22/2013 10:56 AM

I purchased this for my 2003 Envoy XL 4.2L V6 for towing mostly. I also have a K+N cold air intake. My wife and I have noticed a difference in shifting gears, lower RPM's in regular driving and towing, more power where it needs to be, but have not seen a drastic change in fuel economy. Have only had it installed now for 3 weeks. I would certainly recommend this to anyone.

Glad I purchased.

Reviewed By Robert M (Pocono Pines, PA) Reviewed for a 2011 GMC Acadia —2/4/2012 10:49 AM

I looked at a few other types. Glad I got this as it fits perfectly below my radio and the Adjustable light/color setting are terrific. Also having it automatically go on/off, removes the Possible battery issuer. Haven't tried all functions, sure they will be good. Check reviews of all items before you buy. It really helped steer Me to this product.
