Remember its only going to hit max boost for a second before it starts to taper off. Just fyi my car runs at 11.3-11.4 AFR on wastegate pressure 7.2 psi, 11.5 almost on the nail at 10 psi and then 11.6 at 11.5 psi. Using the fuel parts supplied by sasha, bosch 750s, the 340lph pump and the wiring harness. At some point I will get my ecu reflashed so I can data log, a local shop is getting their dynojet installed now, then I will do some power pulls and see where I am at psi on the fuel pressure. Vince told me if I wanted to go e85 I would need 1k injectors, but there is only one e85 station in my area, and it is still a 30 minute drive, just not worth the hastle for me.

My car runs a bit richer than yours but otherwise the same. Mine will run right around 10 under load actually, however knowing that your getting close to the limit of the fueling system is a bit concerning.
I also try and watch the AFR closely but you know sometimes when your spirited driving its impossible to keep as close an eye on it as you would like.
I also agree with the 1000cc injectors, unless someone else knows something I don't there should not be any issues with running larger sticks as long as the tune is calibrated accordingly.
