Turned off the AFM, stiffened the trans 50% made few other adjustments. The AFM in vehicles is a joke! I have driven roughly 1000 miles since I programmed my suburban and I am getting better gas mileage by 2mpg (not much but better). I have no other mods to my burb at this time. Definitely better get up and go from the low end. Shifts feel a little stiffer. Actually fun driving the suburban now. I drove it for 26,000 miles before the programmer. I can feel the slight changes in the drive.
