Super AFC

does anyone have or know if the S AFC really works?

if you tune it correct

how much could expect to gain?

it doesn't do anything if your car is stock or close to stock. The only time it does anything is if you have aftermarket forced induction or major all-motor changes such as ported heads, cams, raised compression, or bigger TB & Intake Manifold.

i beg to differ
