So I took my car to be dyno'd today just to see what kind of numbers I'd get. I was pleasently suprised to say the least! Boost is set to 13psi on the stock turbo.

hitting 13psi then creeping down? nice numbers though

any of you guys able to hold that psi all the way through the rpm? when i had a stock turbo i could get it to 12psi, but it would fall off with rpms.

Right, 13psi but it will not hold that all the way to 7000. As of now the only tuning is via the TOP SECRET rommed ECU that came with the clip. I have an e-manage ultimate wired in but all the settings are 0'd out. Next time I may bring my laptop and try to smooth out the afr. Not very concerned about it since it runs well. I had 3 pulls done and each time the afr's looked almost identical so I assume TOP SECRET did it for a reason
