Works good in a 07 tahoe. Fuel mileage went up, got more speed. Motor runs smoother.

This WZruibo RA003 AFM/DFM Disabler Active Fuel Management is an innovative device that really works right away. Just plug it into your OBDII port and it turns activates to disable the AFM on your v6 or v8 vehicle. Compatibility varies to be sure to check if it’s for your vehicle but otherwise it functions as described. I haven’t had any codes pop up but did immediately see an increase in power when driving. Great product.

I purchased this for my father and he said that it works great. I was completely unfamiliar with the product and had no idea what to expect but it was super easy to figure out.

Ended up returning this. Yes it would keep my 2018 silverado in v8 mode but it also activated my grade braking and when activate it would put the truck to 5000 rpms. Had a hard shift as well. Took this out and the truck went back to running like normal.
