Review on πŸš€ Range Technology Green AFM/DFM Active Fuel Management Disabler Plug & Play for GM Vehicles RA003G by Drew Diaz

Revainrating 4 out of 5

It's expensive, but it works.

My 2012 Yukon XL uses about 2 liters LESS oil between changes now that I keep this thing plugged in. AFM - Costs more oil and spark plugs than you saved at the gas station by shutting off half the engine to get 1.2 more mpg on the freeway. Fun. Every GM truck should have one of these.

Pros
  • great product
Cons
  • dented
