Just when you think you've got it solved.

I've noticed my boost creeping back down again in the space of 1 week.

The Dawes is just about screwed right in.

When I pulled the Dawes apart last week, the only thing that I could see wrong was that there was a reasonable amount of oil in there. I didn't stretch the spring, just cleaned and re-assembled.

I'm still using the original hose clamps that Nissan use on the turbo pipes, would it worth using better ones? If so, what type?

The vacuum hose I'm using is 6mm, but it's softish. Could that be being sucked closed? I noticed it's way softer than the original vacuum hose.

Can anyone remember how to set the needle valve? I can't remember the procedure. I didn't do this the other weekend.

Thanks fort any help.
