boost problem...any ideas?
First a little detail of my setup...
Rebuild Jspec motor with street port
660cc secondary injectors
walbro pump
g-force re-mapped ecu
K&N filer on stock TID
bonez cat
Apexi N1 single
Normally it makes about 12psi peak and falls off a bit towards redline, but recently boost response is reduced, and peak boost is lower. I can get 10psi in 4th gear but in first-third it doesn't want to get past about 8 psi and builds pretty slowly. Any ideas?

oki man I got the same problem as well
you could have one of 3 problems
either sometihng is opening your wastegate
or u got a clogged cat or any exhaust system part
or finally the one u dont want to hear is the turbo itself is getting weak and cant produce good spool (that was my problem by the way)
