PE Twins with Nismo Exhaust?
TT with a too restrictive exhaust will prevent them from spooling quickly and reaching higher boost.
I think you should upgrade to a true dual, at least 2.5", 3" preferred. I have the true dual 2.5" from Altered and it looks 100% stock. I am/was told that the dual 2.5" exhaust will become too restrictive for TT past 500whp so take that for what it's worth... if the Nismo is a single then you're probably going to have issues reaching higher boost altogether.
