I only used it for one day because the truck is in the middle of an oil consumption test that still has 1,000 miles left. It did as advertised keeping the vehicle in V8 mode. On side effect that was unexpected was the transmission that has shifted erratically since new was shifting smooth? Coming up to stop sign the truck would act like I still had my foot on the gas. That went away also. Can't wait till I leave the device in permanently. Well worth the money.
Goodbye AFM, Hello Full Time V8
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.
