right basicly iv got a v1 wrx classic, running a CA sti ECU

it seems to hold back top end then clear after afew secs

according to the crap TIM boost gauge its only running 0.3 bar of boost, which is actuator pressure? iv checked and cleaned the solonoid, it clicks in service mode etc, also the actuator is reasonably stiff, im guessing the 3 port valve is goosed? i havnt done any work on the car personally as i bought it with it already done.

cheers
