I drive a 2014 chevy silverado 5.3L Have had it a little over a month, keeps my truck in V8 mode 24/7. Have no issues with it. Ive seen people say there fuel mileage increased. Mine did not. I used to get around 23-25mpg. Now I get 19.5mpg. Which I completely expected with it being in V8 mode all the time. No complaints. Good buy.

got this when my mechanic friend told me about it when he was diagnosing my misfire issues. I plugged it in immediately and could feel a slight increase in power with no engine hesitation. My pick-up no longer switches into V4. I haven't noticed a big change in MPG's.

Installation takes just a few minutes, and the unit sits neatly and compactly without taking up space. I had been looking for a simple solution that didn't require ECU reflashing or mechanical modifications, and this product delivers exactly that. Be sure to verify vehicle compatibility before purchasing, as fitment varies based on engine type, model year, and transmission configuration. All in all, it is a well-designed, easy-to-install accessory that performs reliably in everyday use.

The plug-and-play design makes installation incredibly simple, requiring no complex setup or specialized tools. Once installed, the driving experience feels smoother and more seamless. I really appreciate the convenience of being able to easily install or remove it at any time. Although it is a small device, it delivers a noticeable improvement to daily driving. I am very satisfied with its quality and performance.

worked perfect on my Camaro 2018

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.
