If I want to tighten the spring as tight as possible what way should the nut at the back go?
Should it tighten clockwise towards the dump valve, or anti clockwise away from the valve to the point it almost comes out?

My boost levels seem to make it leak, so I need get it as tight as possible and take it from there.
Cheers Kevin

 

You need to make the screw go in so that the spring is being compressed, therefore making it stiffer to hold more boost.

So you need to turn it clockwise...

Thats what I thought, just needed it confirming,
Thankyou Kim
