I'm having intermittent problems with boost at the moment but I'm in the middle of trying to sort all that out. If I rev the car in neutral the boost gauge vacuum reading will never reach zero, only slightly moves and I'm certain it should reach zero when revved even whilst under no load. Secondly, when the cars under load the boost gauge will take a long time to reach the boost pressure again after a gear change when normally this is pretty instantaneous?

Is this highlighting a vacuum leak atall?
 
Probably telling you the boost gauge pipe has a leak tbh... what type of tube is it? silicon or the clear stuf?

Silicone hose, binned the clear stuff it came with as it's Known for being rubbish
 
check the connections and as above check for holes. stick some compressed air through it and see if it reads better
 
is it fed from a supplied T piece which has a small reducer inside it? a lot ohave this to try and prevent gauge "flutter" but the side effect is its slow to respond.

OR leaky as tufftys says
 
Wish I'd seen your comment before today badger, that's exactly what it was! And found it after testing everything else unfortunately. Fitted a spare t piece I had and it works perfectly, however now have a bit of flutter with the needle so is there any way of preventing this without restricting it like the previous t?
