I have been having major probs setting the boost correctly on my 3 door but eventually located the problems to the actuator being firstly a split diaphram and secondly the wrong PSI spring.

I have now replaced both of these and have now managed to get the boost right down (previously it was boosting at 22PSI)

ok so after adjusting the actuator the best i can do now seems to be 15-16PSI

Mine is running stage 1 for which i have been advised 14PSI my question is will i be ok running it at the current 15-16PSI as to be honest im fed up trying to adjust it anymore!!

Cheers,

Mark
