I went to Forcefed Industries in Columbus on Saturday to tune with my S-AFC. After some tuning, I gained 22 RWHP and 20 RWTQ. I didn't change anything, other than installing the AFC since last time. Thanks to Tony and Tom at Forcefed for the help. I was running 25 to 26 Psi on straight pump gas. My A/F curve was a very safe 11.5 to 12.0 throughout the RPM range. Without the AFC, it went off the charts rich, like 8.0 to 1 or less.
