Works great no programing just plug and play
I drive a 2017 Chevy Silverado with the 5.3 V8. This device is super simple to install and it starts to work right away. Keeps the vehicle from dropping to 4cyl to 8cyl which over time is hard on the engine. This product is especially helpful with city driving or if your driving short distances. I noticed a big difference right away. My only regret is not getting it sooner! Highly recommend.

This is the one you're looking for
Installed in my 2013 Chevy Avalanche. Works great. Noticeable improvement in performance. Vehicle often sits for 3 days without use and has no effect on battery. Fantastic product for half the price of the big name module.

Worked good for a while
Worked well for 2 years then started messing up the electronics-truck would not start, door/seatbelt chimes would not work, etc.

Works as it should
I have had this for a week now works great. I can tell the difference with the throttle responsiveness which is nice. I do wish that I knew what all the lights did on it. There was no directions other than plug it in and drive.

I love it but…
Bought this around a year ago. Worked beautifully until around a few weeks ago. Went to start my truck one morning and every warning light was illuminated on the dash as well as none of the gauges worked. It missed really bad and I turned it off. I unplugged this device wondering if it was making my truck run that way and it was. I cleared all the codes and drove without it for a while. I plugged the same one in a few days later and it did the same thing. I ordered a new one and it works great so far. Not sure why the other one shorted out but it’s a great product overall.

I bought this dabler for my 2014 gmc sierra with a 5.3l v8. So far it works great! the truck is now shifting smoother because its not having to shift due to afm kivking on or off, and certainly saves wear and dear on the torque converter this way. my gas milage has decreased slightly on the highway as expected, but not ebough to really be an issue(i.e 11.5 liters per 100 kms instead of 10.9 l per 100 km difference), but i've noticed something else. my gas milage in-town has vastly improved. The one thing i will warn you as i found out the hard way a couple nights ago in our -40 cold snap in Alberta, you must unplug this module when it gets down below -30 celcius, or it may wreck the module and kill your battery in the process. luckily after mine warmed up for 24 hours, it is working again.
