  • Bought for my 2015 1500
This is the best thing I’ve bought for my truck yet. I am not paid in any way to promote this product. I will update in a year or two how it has been long term but so far, this thing has made my truck feel like a real truck. I have much smoother shifting and the truck no longer has a weird squeak when jumping back into V8 mode. My acceleration has improved greatly and ironically enough, after disabling the AFM my average fuel consumption has gone down. Definitely suggest buying this if you have AFM. I listened to the instructions at disconnected my battery before installing. Not sure if it’s crucial but knowing electronics, it’s always best to boot up everything together rather than just shoving something in midstream. ... show more

  • 2009 Yukon Hybrid 6.0
I had all the DOD headaches! So I removed the DOD camshaft, lifters, oil feed manifold and plugged all oil galleys that fed the lifters. My engine ran great! However, the ecu on this model cannot be programmed to turn off the DOD. The problem this causes is that the ecu turns off the injectors to the four cylinders when it calls for 4 cyl mode! I was concerned about buying this disabler because although I didn't want the 4 cyl mode to kick in, I DID want the auto stop feature to work. This unit works great! No DOD request from the ecu AND the auto stop feature works perfectly. I am currently getting 19.5 miles per gallon. Don't be afraid of buying it. I've been using it a month now with no problems. ... show more

  • Easy and effective!
I received this today and couldn’t wait to try it. My 2007 Chevrolet Tahoe has the AFM. Recently it developed a “shuddering” in the engine when slowing down, along with a little feel of a periodic misfire at idle. My mechanic discovered the misfire was occurring in cylinder 4 and was likely related to the shuddering and these were both caused by AFM. Installing is a breeze. However, I did not disconnect the battery as the instructions indicate, but had read other reviews stating they just plugged it in while the engine was off, so I did that. The unit went through a cycle with the lights and then settled on one light on at the end. I let the car sit for several hours as I had some other business to attend to. I then hopped in the tahoe and it fired right up, and took it for a drive. It performed excellent. Love the feel of the V8 all the time. Shuddering completely gone with no V4 at any time throughout the ride. I still felt a little periodic misfire at idle, but that’s likely a lifter that is sticking a bit. My only regret is that I didn’t plug this in at 100,001 miles as I believe the lifter sticking (which is the beginning of the end for the motor) is due to AFM. I currently have just over 200,000 miles on the car and engine and with this device I just might make 300,000. If you’re looking for an AFM Disabler, this is a solid pick at a good price! Let’s see how it does over time…. ... show more

  • Removed eco mode instantly
Easy install, no hick ups . Installed the unit and went for a 150 mile ride. My Chev (2017) Silverado 5.3 went into 6th gear (when no load) and stayed in 8 cyl mode. Had at some time a 20mph head wind and up and down a 5500 foot elevation pass. Ended up with a 19.5 mpg. Not bad. Would like a unit that you don't have to remove when not in use ... show more

  • Great Device for Much Less than the Better Known Brand
I am so happy with this thing that I actually could not wait to do this review. Having my 2015 Silverado 1500 Z71 with 5.3 engine for more than a year now, this AFM disabler is the best thing I have done to it. Like many others, at first I thought the AFM function was fairly neat. A way to save a bit of fuel. But, although it is a consideration, do we really buy V8 trucks to go into 4-cylinder mode? As many others have suggested, including the manufacturer’s instructions, I didn’t plug this thing in until I first disconnected my negative terminal from the battery. After that, one push into the OBD port and then reconnect the battery. Took all of 15 seconds. Don’t be put off by the simple packaging and one-page instruction sheet. That is all you need. I let it stop flashing and proceeded to take s test drive. Highway speed or moderate to heavy acceleration was never the problem. My complaint was the transition to 4-cylinder as I drove through the 20mph areas where I live or when gently trying to accelerate after a near stop for a traffic light. That is when the AFM made that annoying pop from the exhaust, custom run duals behind the passenger side rear wheel, and there was a delay in acceleration. No longer! It was immediately better. Drove the same street where it ALWAYS went into half-engine mode but this time the display indicated the V8 was always active. It kept the throaty sound and actually pushed better at slow speeds before I needed a heavier acceleration. As I stated previously, I instantly felt a difference. Now, for the skeptic. I was so very close to getting the Range AFM many times but could never quite bring myself to spend the $190 or so on what I thought was a “maybe it will work” situation. I found this one and, after reading many of the reviews, decided to try it knowing I would return it if it did not work and then buy the more expensive one. I don’t care what it’s branded. I only care that it was approximately $60 cheaper than any other one and that it works exactly as it should. If it fails, I will update this review. For now, though, I am very pleased and will tell anyone that it was the most quickly apparent improvement short of a custom program job or a new set of lifters, cam shaft etc. for my performance. Take it or leave the blue light glow on my foot well. I don’t really care for it so will probably put tape over the LEDs. ... show more

This product has worked great so far. Out truck remains in V8 mode. The product was easy to install as well.
