sorry to confuse u all.. im running a external wastegate, (no dumpy) ct9 hybrid @ 0.8 bar no boost controller, external wastegate runs off a spring never had a problem with the car like this before, it was totally fine since parked up.. (parked up for winter) i start the car up ever other day to keep thngs smooth.. blits power meter is removed, bt i know ths has nothing to do with the problem my mate who had the car before says maybe its because i havn driven it for a while???
