what kind of gains did anyone feel with a afc?

alot

. how much "you feel" is all dependant on the suporting mods you have done. lets say for example you have TBE, MBC, INJECTORS, FUEL PUMP, INTAKE,CAMS, and RACE GAS you are going to feel or see alot more whp then if you only had TBE. on a stock car i would say the afc could yeild 10 whp with a good tune.

rember the afc is just as much or more of a timing mod as it is a fuel mod.

On 93 octane with just a muffler delete pipe and a K&N drop-in, and my own homebrew pocketlogger tune, I can say the car really comes alive above say 5500 rpm where it just rips the rest of the way to redline. The top end "dead spot" is no longer a problem. Also, a little extra fuel at the torque peak smooths out the power band a little. "Feels" faster to me, but how much horsepower is added I don't know without ponying up $ for dyno time.

With a turbo back w/ highflow cat, intake and a SAFC II I gained about 12whp with the afc. My first pull un-tuned made 294whp, then after a little tuning made 307whp 310 ft-lb on a superflow dyno.

Nice, do you have an 05'+ Evo. There was someone else that same day that did a couple pulls because he just got a flash and he had a TB, intake, IC pipes, header, fuel pump and the boost set to 20.5 and he made 285whp on his 03'. Thought he wound have made more. I'm going to tune my car again this week hopefully because I got a boost controler and lower IC pipe, we'll see what happens.

Yeah, it was new to me too. it is at a shop that a few meets have been at, so talking to the owner( he owns a IX and is a licenced AEM tuner) I decided to have him tune my car. The superflow is supposed to read lower like a dynojet.
