Mixed feelings after road tests…
Boost AFM/DFM Disabler ReviewFirst off, at least according to the dash readout, this Boost Unit is doing what it is advertised to do and disabling V4 mode. However below are a couple observations and the results of some rudimentary road tests I did that others might find helpful.Some background: I installed this on a 2014 GMC Yukon XL with 177K miles on it. Whenever I repair a vehicle or want to test the performance, I have a 25 mile loop that I run that is approximately 5 miles city driving (1/2 @ 25mph, 1/2 @ 40mph), 10 miles on a 60mph state highway that includes going over a hill that rises to about 400ft above the low point of the road, and 10 miles on a 55mph country road with multiple curves you need to slow down for. This allows for testing of acceleration, up hill, down hill, cornering, etc. I ran this loop multiple times to test with and without the boost device. I cleared the trip computer average fuel economy between each run. See results below.1. First of all, you do not need a device like this in order to accomplish keeping the vehicle in V8 mode. You just need to run in “M” instead of “D” and put your “M” setting to one less than the highest gear you have. For example in my 2014 GMC Yukon XL, the highest gear I have is “M6”, so to stop the vehicle from going into V4 mode, I just have to choose “M” instead of “D” and then use the “+” button to set it to “M5”. If your vehicle goes up to “M10”, then you need to use “M9” to disable the V4 mode. I have tested this on multiple runs, and even in traffic it never goes into V4 mode.2. After I plug the Boost unit into the OBD2 port, I noticed that the RPMs stay higher on average than when I do not have it plugged in. It seems to be somewhere between the default factory RPM settings and the RPMs when you are in Towing Mode. However, this seems to make the vehicle more responsive when you push the gas pedal.3. In my case, the Yukon gets better fuel mileage consistently in “M6” and is more responsive to the gas pedal than when just in “D” (drive). For my vehicle, when it is in “D” it tends to bounce between gears more frequently when cruising at highway speeds, whereas in “M6” it more consistently stays in the top gear when cruising at highway speeds. There must be some difference with how the computer handles “D” and “M6”.4. Driving my test loop (see above) without the boost unit and the vehicle in “D” (vehicle went in and out of V4 mode multiple times), the readout on the dash showed the trip averaged 20.3 MPG.5. Same run without the boost unit and the vehicle in “M6” (vehicle went in and out of V4 mode multiple times), the readout on the dash showed the trip averaged 21.3 MPG.6. Same run without the boost unit and the vehicle in “M5” (vehicle never went into V4 mode), the readout on the dash showed the trip averaged 20.9 MPG.7. Same run with the boost unit and the vehicle in “D” (vehicle never went into V4 mode), the readout on the dash showed the trip averaged 18.9 MPG. I noticed that even with the Boost installed, the vehicle was still a bit laggy when starting off from a dead stop.8. Same run with the boost unit and the vehicle in “M6” (vehicle never went into V4 mode), the readout on the dash showed the trip averaged 19.6 MPG. Perceptually this had the best throttle response of any of the combinations.So in my case the best fuel economy with V4 disabled was achieved without the Boost Unit, and the vehicle in “M5”. This also perceptually gave the 2nd best throttle response. However, this Boost Unit definitely at least perceptually improved the performance of the vehicle, most noticeably when I had it in “M6”.This was not a controlled experiment and the traffic varied between each run, but I did not spend significant time just idling on any of these runs. Your results will likely vary from what I got, but I thought this would be useful information for those looking at purchasing this unit.

Get what you pay for!
Love how simple and effective this device is! Quality is great. Throttle response is night and day, no more lagging shifts when you stomp on the pedal, and no more ticking while idling. Helps me post pone the AFM delete until I have the money. And the light on the device is so dim you can hardly tell itâs there. I bought an OBDII extender and zip tied it under my dash to hide it away and still have access to my OBDII port for diagnostic purposes if needed. Love the product! And MADE IN USA makes it even better!

Made In America so it actually works.
2016 Silverado 5.3 8spd with 100k. So far I’ve gone 500 miles with the device. It has made an immediate difference. I’ve gained roughly 2mpg, stopped rough idling and erratic shifts. Great product – spend the extra money and by the American made product.

Itâs easy and really works!
Works! Thatâs all I have to say! You unplug it you go back to factory settings. Now my truck stays in 8 cyl like it suppose too! Gas mileage made no significant difference what so ever. Why ruin your lifters? To save one gallon of gas maybe per tank?

Functions and performs well.
Plug and play easy installation. Performs perfectly. Disables AFM seamlessly and seams to tune transmission shifting to optimize fuel efficiency. I am pleased with my purchase of the Boost AFM disabler.

2 week update!
(two week update) with me running the boost AFM disabler, four days into having the unit plugged into my truck as the below review says I did notice an immediate difference until the engine blew up now I can’t say that that was because of the AFM disable But as of right now it’s in the service department at the dealership and I do not know what’s wrong with it but it had to be towed there !(Original review)This works perfectly it’s much cheaper than it’s competitors it’s made in the USA tested on American trucks it’s fantastic it made a difference in my engine immediately it sounds better it runs better my transmission shifts better the truck is just overall 100% better. The only thing I would recommend is to get the flat extension cable for the OBD two port so you can chuck this unit up under your dash zip tied to a wire harness because it’s light blue it kind of sticks out like a sore thumb and there’s a green light on it when it’s operating so at night it could be slightly distracting but overall I would purchase this again and again again and again

Simple, Easy, and works as advertised
Was looking for a produced to disable the AFM in my 2018 GMC Sierra and most people recommended the Range Technologies product. I canât speak negatively on the Range Technologies product given I didnât purchase it however, the Boost plug in is cheaper and works as advertised.The AFM is disabled while the module is plugged in to the OBD2 port. Some people wrote the module stuck out far and would get hit by your leg. I have no issues donât even notice it. 5/5 would recommend.
