Goodbye AFM, Hello Full Time V8

Reviewed By David M (ANN ARBOR, MI) Reviewed for a 2007 Chevy Avalanche —3/28/2017 8:41 PM

I was a bit hesitant to buy this product as there were no reviews for it, but for the price with coupon I couldn't resist. device works perfect. Simple plug and play installation to disable the AFM. My v8 is finally a full time v8. My only complaint would be the red lights on the unit. It lights up the floor at night.

Good power and Mpg

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.

Works perfectly

Reviewed By LAWRENCE M (COLUMBIA, PA) Reviewed for a 2008 Chevy Avalanche —12/15/2016 11:32 AM

Plugged my Range in right away, started driving, no more dropping into four cylinder mode! No change in fuel mileage. Exactly what I wanted & expected. Newly rebuilt engine in my truck 4 months ago I believe due to the AFM. Gonna keep truck till I go,so we'll see!
