    • Worth every penny
Install took a couple seconds. Went from burning a tank a week to half a tank a week. I do have to mention that I try not to dog it or beat on it as it definitely will get worse gas mileage. If you have aftermarket exhaust, it will sound 1000% better with no helicopter noise. AFM is a waste or time and destructive to your engine. 5 out of 5 and would recommend to everyone ... show more

    • Stop Your Chevy from De-activating Cylinders that could lead to costly repairs!!!!
I use this in my 2008 Chevy Silverado 1500. The V8 engine has cylinder deactivation where it turns off 4 cylinders to save gas. This has no to have problems in the first years of these engines, where a valve can get stuck and increased oil consumption. To get the valve free can be a costly repair. This tricks the ECM to tell it never to put it in V4 mode. Therefore you never run into the problem when you have it plugged in. It also gives you your full V8 power all the time and you don't get that engine "bog" when you step on the gass and it hesitates to change it from V4 to V8 mode. I have been using it for roughly 6 months now and like it. It is a bit pricey for such a small device, but I rather pay the $200 now than costly repairs later. ... show more

    • Great purchase, saved vehicle
We bought this because we were starting to have afm lifters tapping and we were burning through multiple quarts of oil a week. After installing this and driving the vehicle for a while we did notice a like .2 mpg loss we almost don't burn any oil and the engine runs so much smoother. At some point we may have to replace the afm lifters but that won't be for a long time. We also installed the new driver side valve cover and that seems to have helped aswell. Overall if you own a Chevy or gm product with afm buy this. It will extend the life of your vehicle and make it run so much smoother and cleaner. ... show more

    • Instant improvement to performance
I thought this must be too good to be true, but based on other reviews, decided to try it on my 2008 Chevy Tahoe 5.3 with 127,000 miles. I did not know that my Tahoe had come with AFM. I started hearing some lifter noise and was getting stumbling and check engine lights on hard acceleration. As this could potentially be a very expensive repair, I figured I had nothing to lose. Just plugged this into the outlet under the dash and could immediately feel improved throttle response. And it sounded like a real V8! It kept improving throughout the following week and now the lifter has gone away. It's now two months later, and the Tahoe has never run better. Plus, my gas mileage actually improved slightly. ... show more

    • I now have a real V-8
2009 Tahoe with 155K miles on it. No signs of AFM/DOD engine issues and my mechanic advised me to asap stop the V8 to V4 before issues show up. Of course he advised me to do the complete engine delete but since there are no engine or transmission issues this was the best way to go for now. I really like the feeling of having all 8 cylinders operating together. Love it. ... show more

    • Could be cheaper, but does what its supposed to do
So far so good. Plug and play. No engine lights yet. Keeps it in v8. Has sat for 3 days at a time plugged in and no battery issues. Haven't noticed any gas mileage difference cause I have a heavy foot all the time. If in canada, and you bought from amazon, range will still give free updates, just pay for shipping. I will update the review next season. ... show more
