S-AFC on an auto does help. I got a noticeble improvement by leaning out my fuel curve a little in the 3500+ RPM range. Pulls a little harder in the powerband. I'm still non-turbo (hopefully not for too much longer). If you get a turbo this is a must or some other sort of device that allows you to control the fuel mixture.
