Review on TECHNOLOGY AFM DFM DISABLER COMPATIBLE MOTORS by Chris Sanders

Availability Installed a few days ago on my 2015 Sierra. I was sure it would disable V4 mode but was curious if it would offer all the other benefits I've heard from reviews. It looks like it works, not ticks. It looks like it will affect the shift points as well. The truck just shifts smoother and feels a bit more aggressive. It's really more than just disabling V4 mode. Trucks drive much nicer now. Just plug it in and you're done! No need to talk about error codes just yet. 5 stars for me.
