Help: Losing Boost

It seems after 5000 rpms, my boost drops from .8 or .9 to .6 or .5 - and I notice a loss of power from 5000 to 7000 rpms. If anybody could tell me what to do or what to look for, I'd appreciate it. Thanks.

I am pretty sure that the ECU lowers the boost once you get into the higher RPMs.

The stock turbo is not big enough to keep full boost all the way to red line. It tapers off as the rpms go up.

true true...but you could always tighten the wastegate...it'll hold a bit better then...but only tighten it a little....and 'test boost' it after every 1/4 turn or so
