You really don't want AFM. In the early years it caused all myriad of oil ring issues and massive oil consumption problems.
In 2008 GM changed the Hummer H2 to the L92 / 6.2 / 400+ HP engine, but the mileage stayed about the same. I have an 04 and it gets about 13MPG and my 2010 Suburban 2500 with the L96 / 6.0 gets about 13 MPG...........Heavy trucks = lower MPG.

As others have stated. AFM is a death sentence. Google it and go to cargurus.com and see how many people (including myself) have lost motors due to it ruining lifters. You don't want this.
