Here is what is happening now after intercooler installation and upping boost from 12 to 14psi on the TCD S2 kit...
As the revs climb, the AFRs climb to about 13.9 in the midrange, and then drop back down to about 12.5 as it approaches redline. I turned in the FMU's bleed screw a quarter turn, then a half turn, and finally a full turn, and it did not seem to make a difference. Therefore, I backed the bleed screw back out all the way again. I don't think I'm running out of fuel capacity, because it looks like the normal 12.4-12.5 near the redline...
It runs hard, but obviously something needs to be adjusted. I figured it was the FMU bleed screw, but I really don't know. Do I need to turn in the bleed screw more so that the richening comes on sooner? Suggestions?

What "bleed screw"? The one on top of the housing? If so, that controls rise right at atmospheric (0 psi), and has nothing to do with rpm. The only way to adjust the mixture with regards to specific rpm is to get a custom chip burned or use some sort of piggyback system. Standalone being the ultimate solution of course.
