S-AFC should be professionally installed and tuned. It needs to be tuned in a dyno shop.
First run would be the base run (get stock dyno numbers) 2nd run would be with adjustments where the tunners see where you air/fuel curve can be improved and he makes adjustments. You should not be using other peoples number because every car is different, the adjustments are different.
Besides the adjustments on the S-AFC is on the RPM even at 1000 RPM not just where Lift kicks in.
