This things works great! Super easy to use, awesome design. I like how sleek and nice it looks. Just plug in and go on your way
So far it does what the seller says it does. I believe that covers it!
This product is absolutely fantastic for us off-road enthusiasts! After installing it in the car, the vehicle stays in V8 mode all the time, solving the issue of throttle hesitation between V4 and V8 modes. Love it!
Works as it should. Easy install
2019 Trail Boss 5.3. As advertised. No more v4. Great product!
works good thanks
Works as advertised for 2016 Corvette Stingray. Installed after disconnecting battery (negative terminal lead) - just plug it in and reconnect battery lead. Took a two hour trip and didn't see V4 not once. Car runs smoothly - no more shuttering because of cylinder deactivation. Smooth sailing. Money well spent.
I have a 2014 Silverado with the 5.3. Since plugging this in it stays in V8 mode all the time.
Just got a package, but man, it looks like it went through a pancake press at the delivery depot. Ain't exactly the kind of greeting I was hoping for. fortunately the product is fine
Seems to work well, the device installs very easily, but there are times when you have to take it out, like for emissions tests or to use a code reader. Otherwise, it does just what it's supposed to do. I believe the gas mileage has improved by a mile or two per gallon for short trips. Can't wait to see how it does when we take one of our cross country trips!
The structure seems solid. I’ve used it on my Sierra 1500 for about two weeks, and the engine has been running smoothly in V8 mode non-stop. The nighttime drive lights are just right and not blinding. However, I’m always a bit cautious with these gadgets and wonder about the long-term fuel efficiency. From my experience on the road so far, I haven’t really noticed any dramatic fuel savings or increased gas consumption. But as it keeps my engine chugging along consistently in that V8 mode, it’s good for now.
2018 Silverado est with the 5.3 engine. This thing so far has worked perfect. Keeps the truck in constant v8 mode and smoothed everything out, it's much better. Gas mileage went down some but this is worth the trade off to know you engine won't lose a lifter and a came. A+
Easy check out, shipped securely, easy to install. What more can u ask for. Love it
They sent the wrong part initially. They corrected the problem and resent the right part in a timely manner. The AFM disababler works as expected. Truck seems to run much smoother.
The device works as advertised. Happy with product. And I hardly lose any gas mileage!
Well for one make sure what you sell works, my afm doesn't that's it that's all
Doesn't work
Product did not work. Put it in two different trucks and nothing. Unfortunately I threw box out before trying it. My bad.
So far so good wish I could tell.more if it was actually working a little decrease in mpg because of it staying in full v8 mode
Plugged it in caused 48 codes and the truck to become undriveable
It drained my battery in a little over one day. Guess I will have to unplug it every time I don't use my P.U.
Kills the battery within 10hrs if it stays plugged in. Drops it from 12v to 4.5 to 5.1 volts
So far so good. I put this on a 2015 Silverado I bought that has 220k miles with no ticking. I'm hoping this AFM disabler will keep it that way. So far shifting is smooth and it's staying in V8 mode.
Seems to work as it should no longer goes to four cylinders other than that no real noticeable change
Works as advertised
Does exactly what its suppose to do.
Works OK revving higher to shift gears
So far so good. I have had it in about a week now and everything seems to be going pretty good. Truck is starting in v8 mode and driving very well
This thing drains my battery down sitting over night I have to unplug it every time
Does what I wanted. Good price also
arrived well packaged, installed a few days later. So far everything appears to be working perfectly. My only comment is that the led's seem a little dim for my personal tastes.
Looks good plug right in lights came on like it’s supposed to so far seems all right
Transmission definitely shifts better with this device.
This product is amazing! I wish I would’ve bought it much sooner. Before at times when I would let off the gas, they would be a sort of clunk in my transmission, but after installing this product, the clunk is completely gone and the feeling in the pit of my stomach as well!
Sleek design, works good. No issues after 2 weeks of use so far
Does what it says it does. Bout 2 weeks of use and no issues
Works amazing. My MPG has stayed the same so thats good and I can totally feel the difference with the AFM disabled. Definitely recommend 👍
Haven't had a chance to try it/truck's in the shop !
Works exactly as advertised!
