My friend keeps tellin me to get an s-afc (i think is what its called) for my car, he was sayin it could give me 20 hp, do these things work on bmws? cuz all the info he has on them is on supras becuase thats what he has, but i was thinkin about gettin a cam shaft because im not in to that computer stuff. which one do u guys suggest?

Ithink those are like add-on ecu's, or a new program for the ecu. Usually they get rid of rev limiters, change the fuel maps ... same stuff that a Shark Injector (your car is OBDII ?) would do. Not so sure about 20 HP though. You may be better off with the cam shaft ...
