Mine was doin the same, and I never found out why! I dunno if it's doing it now as ive not had the car out for ages, but the hoses from the amal valve to actuator/turbo/metering unit werent all tight and it was overboosting so I put it down to that for now, also fitted a new fuel tank that I should of cleaned out before fitting, so wondered if it was something to do with that also.


I'd take it for a RR setup soon anyway as it's a new car to you and you dont know much about it or it's setup, precautionery if anything but probably well worth it !! Best place up out neckof the woods is AVA.
