I have asked this before, but my car tends to not get full boost till about 4th gear when I set my boost @ about 14 psi. Second, and third gear will only hit about 12.5 psi or so. I am curious if the tiny stock twins are not putting enough load on the engine to make full boost? I have a large street port FYI. Fourth gear pulls like mad, and I can get about 14.5 psi till redline. any idea?
Some people says my twins are a little tired, however, they have probably about 80K miles on them.

your turbos might be tired, or you could be seeing boost drop. What intercooler are you running? Your engine may only be seeing 14PSI, but with a large intercooler, your turbos could be pushing 16 or 17 PSI.
