I've secured that pipe with a proper clip and it's still not boosting properly 
Mind you is it pulling better with the new valve so the old one must have been on the way out, and was probably the reason I was dropping boost from 20 to 14.
I'm gonna pull apart and re-fasten the IC pipework this week
I reckon when I put my foot down the boost is seeping through a coupler somewhere. But wouldn't it misfire if that was the case?
