AFM/DFM Disabler 2024 New RA003 Chevy 5.3 Silverado / 5.3 GMC Sierra Active Fuel Management Keep Engine V8 V6 Trucks&SUVs for GM Yukon Tahoe etc. 4.3L 5.3L 6.0L 6.2L AG003 Pr

worked perfect on my Camaro 2018

I was hesitant to buy specifically one of these unit of this brand just because of "What you pay for is what you get" after reading much reviews for another brand "Range" and didn't want to spend $230+ for something that does exactly the same vs these Amazon brands (signifcantly Cheaper). I have found these Amazon brands to be more reputable with reliability, consistency, and MPG in mind. so I pulled the trigger on one of these Amazon ones instead. I was kind of hesitant to write a review because I was thinking if I should wait a bit to test and trial for this AFM disabler but I did so that it might help others make a decision. But I did order it. Arrived quickly, easy installation. Nothing durable about a unit like this of this nature, it's responsive so far, hence it's working so its compatibility with my suburban is good. Good for it's value. I drive a 2019 Suburban 5.3 4WD LT WITH 107,XXX miles , six days into it so far and I have not seen it switched back into v4 at all. Before I ran the AFM DISABLER, I would normally drive it in the L mode and leave it in L5 and it would never go back into v4 at all but with L5, the engine will rpm around 2500-2600 at L5, hence not get good gas mileage, while L6 rpm will go alot lower around I think around 1500-2000 and save gas more gas but the AFM will engage and go back to v4 BUT! (Just less frequently vs regular DRIVE mode whereas it would be more frequent) With this unit installed, according to the readouts, I believe I have saved a few MPG I want to say around 4mpg more. I use to have best scores of 17.x but with this unit on, I was getting 20-21.3 mpg on the freeway. The picture will help you get a better idea; Speed, rpm, etc So far, Im happy with it, not super stoked about it, but better than having to see the car go into the stupid v4 mode And prematurely damaging the engine. Previously, having to replace 1 lifter, rollers and 2 valves. I am still listening to how my suburban is responding and behaving with this AFM disabler on and connected). I will update review from time to time.

2009年シボレーシルバラード5.3Lへ取り付けいたしました。 V8から切り替わる事もなく機能しています。 微妙なアクセルコントロール時のV4からV8への切り替わりタイミングで一瞬もたつくようなぎこちない挙動もなくなりスムーズになりましたが元々のコンピューターが燃費を良くするためのプログラムなのかレスポンスはタルい感じのままです。 まぁリフターの固着トラブル対策なので少しは役にたつのかなと思います。

Perfect, work as it should do, no problems at all.

I will start by saying that I am a retired mechanic so my review might carry a little weight. With that said, this disabler works great. I have a 2018 Sierra 1500 and I was a bit skeptical because of some of the reviews, but I have had zero issues after one month of using. The exact opposite, actually. No more bogging down on 4 cylinders. The throttle is much more responsive. I installed a cat-back Flowmaster exhaust system because the original GM muffler rotted out on both ends. The drone from the AFM was driving me nuts. The issue has disappeared. I was expecting a bit lower gas mileage, but it's actually better now. Before using the disabler my average fuel economy was 17.5L/100kms I ran it for 100kms after installing the disabler and it dropped to 15L/100kms. I also let the truck sit for a solid week to see if it drained the battery. Before starting it I took a voltage reading at the battery and it was 12.6v, so no parasitic drain from the disabler. I didn't experience any check engine light as some others mentioned. All in all, I consider this disabler to be one of the, if not the best purchases I have made for my Sierra. I 100% recommend this product.

Just wonderful. No more rough downshifts and hesitation when I step on the accelerator. Much smoother drive. I got it for my 2020 sierra 1500 with the 6-gear transmission.
