Made my 2007 Chevy Silverado 1500 with the 5.3L engine run so much better! Not as many hard shifts, doesn’t miss as much as it was before the tuner. Thanks

Several friends recommended a AFM disabler for my 2007 LTZ Avalanche. I read a few reviews and decided to purchase this one. It plugs directly into the port under the steering wheel. No tools needed. I've had this device for a few days now. First thing I noticed was that my gas pedal was much more responsive to my foot on the throttle, no more hesitation. Can't speak much on the gas mileage, but I can say my truck sounds and drives much better than before. It does have a red light that shines while the truck is on, but goes away when the truck is off. The red light is pretty bright at night, if you don't like it use electrical tape. I'll update should something go haywire in the future. But until then, this has been a solid purchase and upgrade.

Love the Diablo module! Smoother idle, increased power, and better oil pressure! I installed it on my 2013 Chevrolet Tahoe PPV. Super easy install! Plug and play! The perfect canned tune! My truck is a whole different animal when I run this. The best part is you simply unplug if you want to disable the device for long road trip mpg's. I'm hoping it will cancel, or delay the costly rebuild of a DOD delete in the future. Doesn't drain your battery while sitting. The led light turns off with the key. I left it plugged in for a week in winter temperatures, and it fired right up. A better option than the Range, because it is possible to update it. That option was worth the $19 cost difference. $208, I wish it was more affordable, like $100 lol. Probably cheaper than having it tuned at the Dealership though.

2014 GMC Sierra 5.3L. Bought this truck used with 20k miles in Nov 2017. I was not happy with the AFM after driving it for several weeks. I had observed huge clouds of smoke on occasion when the AFM kicked in or out. Big blue clouds of burning oil. Dealer stated they couldn't find anything wrong. Also, the truck seemed to shift very unevenly and the AFM kicked in and out frequently. So I took a chance on this AFM delete module. 90 days in and I am quite pleased. No more burning oil. Shifting is much smoother and the truck much more responsive (hesitation on take off is gone) and this has had little to no impact on my mileage except for long distance expressway trips. With AFM I have hit 23.6 MPG. Without is 20.3. However, if this is a concern, just unplug it before you start your vehicle if planning a long trip. I would recommend this to anyone curious to what the AFM delete can do for them. Now that my warranty is over, I may do the physical AFM delete as I intend to keep this truck for a long time. As you can imagine, that is a substantial amount of work and not cheap making this trial perfect.

Received in the mail brand new, no damage or signs of previous opening. Plugged into my 2008 Tahoe and two days later my check engine light turned off and engine started running smooth again!! So thankful for this product, 100% recommend price is worth the product!

Installed it waited for lights to do thing then started to drive drove for 2 hours nothing next day nothing installed love you in 2011 Chevy Tahoe Did ABSOLUTELY NOTHING!! No difference in shift power acceleration it wasn’t cheep to get and to have it do nothing is very disappointing absolutely waste product is worthless Update brought it to my local mechanic computer geek he said that this is pretty much just a plug-in light there is nothing in it for a software guess that’s why it did nothing for my SUV

I was not one of the lucky ones who knew about this amazing little gadget you pop in your truck and just go before having to replace the screw up that Chevy clearly made. My truck was repaired and popped this little piece in and 100% you can feel the difference. I have a 2010 Chevy Silverado LTZ. My gas mileage is not a noticeable difference. The truck runs much smoother and I couldn't be happier. I am not having any issues or interference with any other components on my truck. Definitely worth the purchase to avoid thousands of dollars in repairs. When I get the truck inspected I just remove the FMD and truck passes no problem at all. Doesn't affect anything but what it is intended for. If you have a Chevy and the flex fuel 5.3L engine I highly recommend you invest in this.
