Range Active Fuel Management Disable Device Reviews


Great Product right out of the box right into the truck.

Reviewed By Randy P (SOUTHSIDE, AL) Reviewed for a 2011 Chevy Avalanche —7/19/2019 8:29 PM

I could tell the difference as soon as I left the driveway. Like driving a totally different truck. So far no difference in fuel consumption. Truck smoothly running on all 8 all the time. Fantastic acceleration and tranny shifting super smooth through all 6 gears. Love it! No battery problems whatsoever. Somewhat on the pricey side but quality device. No complaints at all. If you hate AFM your gonna love this little guy!

DiabloSport Sprint Active Fuel Management Module Reviews


not worth the asking price but works.

Reviewed By Cody M (TULALIP, WA) Reviewed for a 2011 Chevy Avalanche —5/29/2019 3:48 PM

its alright does what its supposed to do and tricks the computer into being under load to run at v8 mode all the time. doesn't solve rough idle issue doesn't increase hp or mpg it only removes the v4 mode. thats it. not worth the money but you got 3 options ,this, the other brand, or buy the tuner. wish i would of bought the tuner now instead of later. if your tight on money but really want your v8 to be a v8 then this works .. but needs to be ALOT cheaper.

Hypertech Max Energy Programmer Reviews


Good power and Mpg

Reviewed By Diego P (milpitas, CA) Reviewed for a 2003 Chevy Avalanche —3/18/2017 10:25 AM

I order the hypertech max tunner for my 03 chevy avalanche 2500 with the 8.1 litter, just to get a little bit more power and mpg, and I was surprised with the results I haven't gone to a Dyno but I definitely feel increase in acceleration and my mpg went up 3mpg more witch is great for the price.
