to help jim out i had a look for at this for him... the hi/low boost valve is'nt looped it just has no pipes connected and the pipes from the turbo and the actautor are pushed onto another solenoid valve which i rekon is attached to the boost controller... it also has a jam racing FCD tucked behind the ECU it's boosting at 0.8 and slightly above that .....so slightly over stock but maybe its due to the weather being cold it maybe peaking a little i'm unsure pretty lost atm myself yup lol
