My 2009 Avalanche runs very smooth now, acceleration is steady and I have not noticed a significant decrease in fuel economy yet in 200 mile yet.

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.

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.
