As above, i have fitted a full decat and am now hitting 20 psi in 4th and 5th i have been told i need a restrictor, can any give me some information where i can get it from and what size it needs to be etc,

Cheers

 

Fit a Dawes and you can set whatever boost you want within the engine's limits. I did it and it was extremely accurate in holding the reduced boost I wanted. My car was overboosting for the same reason as yours.

do a search for restrictor but usualy you will need to bore it out or the other option is use a bleed device aka dawes device or change your actuator

 

How would you suggest to bore out the restrictor. I am also having some overboost problems and off to Germany for the rally on Thursday, so need to fairly quick solution.

Cheers,
