Independent mechanic here. I install these on every GM I work on. It stops AFM cycling that can lead to lifter issues. More people should know about this.

Wish I had done this sooner. My truck stopped bouncing between gears and RPM. With this and E85, it actually feels good to drive again. 100% recommend

No issues, no codes. Does what it’s supposed to. Easy to install and take off if needed. Throttle feels a bit better and mileage didn’t change. Worth it.

After dealing with lifter issues around 100k miles, I didn’t want to risk it again. Put this on my 2015 Silverado and it’s been running smoother since.

Having power ready all the time makes it feel less laggy. The truck responds quicker now, and the exhaust drone isn’t there anymore.
