Considering some of the recent discussions, it seems like my boost has been a bit (~3#) low ever since I installed the SC earlier this year (Aaron's full kit w/ 9# pulley & Si trim). So i thought I'd take a look at my last datalog that I did for Seb from a few months ago. I charted Manifold Absolute Pressure v RPM. As you can see somewhere around 6700 RMP it starts to flatten out. Is this normal for this setup, or should it maintain basically the same slope all the way to redline?

Mine starts to level off like yours. This is Topgunz full kit, stock pulleys, stock filter, long tube headers. Hits 12.76 psi.
