you might be hitting boost cut

ya get an FCD (fuel cut defenser), cause you have an s4 wich cuts off after 8.6 psi of boost. Then anything higher you may want to upgrade fuel pumps, also, rewire it so you are for sure getting full power to ur pump.

get the fcd then youll notice the difference cause you can go over like 5k rpm before hitting a wall.



my friend is in the same situation but is too lazy to buy an FCD. my n/a beats his.
