AFM Disabler, AFM/DFM Disabler, Active Fuel Management Disabler RA003 Compatible with GM V6 V8 AFM Disabler 5.3 Silverado (GMC Sierra Yukon Chevy Tahoe Avalanche Cadillac Escalade) 4.3L 5.3L 6.0L 6.2L

Works gloriously for the 2018 Suburban. Stays in V8 all the time, no battery drain noticed, car starts perfectly and accelerates smoothly. No longer have any worries about damaging my engine from the V4 lifters. Great price for the value. I don’t make product reviews much, but this one deserves it. Thank you.

Works fantastic! It's been installed in my 2013 1500 5.3 for more than 20k miles. No battery drain no transmission issues , nothing but a smooth ride I figured it to loose .2 tenths of mpg. For me that's nothing.2 blue lights when stopped 4 lights when moving.158k on truck.I change my oil every 4 to 5 k.I always use dexos oil 5w30.I would definitely recommend this unit and advise anyone with this engine to change your Oil regerly to help keep lifters from failing.

Works great price right not difficult to put in. Blue lights show it works

I have had it plugged in a couple weeks now in my truck and it works good. Only thing I notice is not all the lights come on when driving

Great product and fairly priced, worked as intended

Works as advertised not to bright at night so works great , easy to use , great for the money , it did what it was supposed to do , increased speed , increased power

Works amazing. All I had to do was plug it in. Before putting it in and hauling my 26 foot RV, on the highway it was constantly in and out of v8 to v4 all the time. Very happy with this product

So far, been a month....it works. I have not seen any negative battery draw.
