Does this AFM disabler work? It seems to; I plugged it in, started my truck and checked the display, the truck is always running in V8 mode. So that's good. I drive a 2007 Chevrolet truck with a Vortec 5.3 V8 engine.What I don't really like is that there are 2 LEDs on the front of this unit; a red and a green. The green one flashes and the red one is solid. I have NO IDEA what that means, and these lights aren't even mentioned in the manual.Most of the time a solid red LED means something is wrong, even though everything is working fine.
Installation was quick and straightforward, and it immediately fixed the performance issues I was experiencing with my vehicle. The build quality feels solid and durable, and it effectively disables the variable displacement system without any complications. Since installing it, my engine runs smoother, accelerates better, and feels more responsive overall. Perfect for anyone wanting to restore full engine performance—highly recommend!
