If you have the SC300 the S-AFC should give you around 25 - 30 rwhp (rear wheel horse power). I dynoed 197 rwhp peak. Someone else (I won't mention who) dynoed 207 rwhp peak with the S-AFC. Very Impressive!
PS. Just found out recently that there is a problem with the S-AFC. The ECU rethards the timeing with the S-AFC so unless you reset the ECU once a month you'll have around 165 rwhp.
i was just going to buy the s-afc yesterday for 300 too! i have to reset the ecu every month??? is this easy? or just disconnect my neg. battery for 15 minutes??? also, do i have to pay someone to program the thing?

I called apexi and asked one of the techs about their expected results on the sc400 properly tuned on a dyno and they said about 4 hp. They didn't believe me when I told him of a sc300 that got 25rwhp.

I would say try it. It's $309 bucks plus the installation and dyno tuning. S-AFC tunes the air and fuel ratio so this won't give you such a big power increase as the ECU upgrade since ECU does timing, does something simmilar to S-AFC (but not as well as well tuned S-AFC), increases the red line and other stuff.
