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

 

Anybody?

 

16psi is normally fine. But only your tuner can answer whether or not YOURS is.

 

Thanks again Stu!!

P.S I dont have "a tuner" lol you are all millions of miles away from me!!

 

I think you car was running a superchips one Mark PM SCC to check boost recommendation.

 

Cheers for the advice Phil.
