    phase 3 and 10psi????

    Hi guys i have a slight problem with my boost at the min. Right i have a coupe turbo with Regals phase 3 and im getting 10psi and 20psi overboost now as to were i used to get 17psi and 23psi overboost. The boost is not all over the place its stays at that what do you guys think is wrong. Also i get a strong smell off petrol sometimes when im parked waiting for it to cool down also i dont have any codes or em light on???.

    Cheers, Graham

    Its on 0 when off and -19 when idle, also checked for split pipes and checked all the vac pipes and they all seem to be fine.
