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.

Turned off the DOD on my Avalanche and gave it just a little more power. Added some pep in its step.

Reviewed By Joshua M (MISSOULA, MT) Reviewed for a 2007 Chevy Avalanche —3/9/2011 11:31 AM

the main difference you can expect to see is a big improvement in how the truck shifts. i installed the tuner in my 03 chevy 5.3L with the premium fuel option to gain the most results i also bought the programmer to change my speedometer for 35s. i have increased mileage about 2 or so with aggresive driving. good product i would buy again.
