Got out to Speedworks today with Damon, Nixit, Aspendog, and Ty. Final results at 23psi (peak at 19psi was the same): 456 rwhp & 470.5 ft/lbs torque Ambient intake temp was 100.2 degrees and 30% humidity. Spent about an hour and a half tuning with the AFC which is very useful. Initial run was extremely lean with the AFC at 0% across the board and looked like this at 19psi (1.3 bar): 
Note how extremely lean above 5500 it gets. After heavy tuning with AFC and having 5500+rpms set to +50% correction (yikes!) yielded this: 
Finally one more run at 19psi got this HP, but the curve went a little funky.
 At this point we figured we'd turn the boost up and see what happened, ready to drop throttle if it got too lean. This was the end result after three runs: 
Note that there was no gain in top end HP but gained ~50rwhp and ~70 ft/lbs in the mid range because of the extra psi. Also note that even with +50% correction on the AFC it still leans WAY out up top. Comparison of initial to final best AF curve at 19psi: 
Comparision of initial run (19psi no AFC tuning) to final run (23psi w/ AFC tuning): 
Not sure why the numbers are low, but it appears after watching the injector pulse widths that I'm maxing out up top on the 555's. I saw them peg 23.1msec and hold that for the last 1500-1800 rpms. Max injector cycle at 6000 for flow rate is 20msec, so I'm totally saturated (at least that's what seems to be the case at first blush). Overall I'm disappointed, but hell, I still have a 450rwhp car :-)
