Hi Guys...i have an imprezza P1

It seems to be overboosting .......i have deffi gaugues to monitor boost and they are topping out at approx 1.5 bar

What should be the normal rise n fall figures ?

should it be holding at 1 or 1.1 bar?

G-Force in aylesbury seem to think its either a turbo issue or a sticky actuator? anyone had this issue before?

they said may need to take turbo off to send away to analyse?

is this a warranty job?

im thinking of taking it to subaru specialists "bulldog" in twyford to let them drive it and diagnose


It drives well no hesitation or stalling etc.....but can hear boost coming on\off

any help appreciated.
