A few days ago I went to the dyno and got some good numbers. The question is that when I was at 13psi the air to fuel ratio was on the lean side. I was running about 13.3 between 3000 and 4500rpm and then dropped to a safe fuel ratio of about 11.5. The red line on the graph in 12.1 it not labeled. What is the normal fuel curve for a S14 black top? The only thing that is done to it is fmic, full exhaust and a manual boost controller. After dyno it just got me nervous about how lean it was running. What would cause it to run so lean? Also would a safc2 fix the problem?
