I have a 2016 Chevrolet Silverado 1500 High Country with the AFM. Got this in the mail today - plugged it in and before I got to the end of my street I could tell a huge difference in the way the truck drives. No more shudder, no more “Chevy shake”. No more super hard downshifts. I am beyond happy with this product. At $180 as well, you can not beat this. If you have any of the problems described above, and before you spend an unknown amount of money at a repair shop, give this little dude a shot. I couldn’t believe it. Excellent product. Thank you Range!

So after being forced to change failed hydraulic lifters 3 times in less than 3 months due to the crappy design of the afm, a friend told me about deleting the afm all together without having to do any actual tuning. So I figured I had nothing to lose and bought it. I’ve had it for about a couple months now and it seems to be working as described. And I have not seen any issues with my battery either. 09 Tahoe

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

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.

I was told by the seller that this had the latest firmware update. Apparently it does not since it suffers with the battery draining issue if left plugged in for a few days and not driven. I would like the seller to make contact so it can be updated.

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.
