i had a problem with overboost a while ago @ 1.5bar
so took the car to subaru gatwick they fitted a bit in the boost/sol tube and that sorted it down to 1.2bar. last week i found loose fitted "y" pipe and induction pipe so tightend all pipes and the boost went up to 1.4bar i then fitted a hks bov "sounds sweeeeet" but now when i boot it boost is just over 1.5bar
was thinking about getting hks evc 4/5 rather than standard as i wanted to also upgrade to an apexi power fc ecu.
any helpfull suggestions would be much appreciated its a sti v3, 6s ecu 311bhp
