cheers pal so if its turned up to 10 psi is that safe i dont put my foot down in my car really its just nice to have abit of power under your feet when u need it pal ,when i took it msd it was running 70 bhp it was shit slow and used loads of fuel he told me i needed to change actuator cos it wasnt holding boost and when actuator is changed i should get about 150 bhp 160 maybe what u think
