Got a bit of a strange problem here!

My boost gauge works, BUT the needle is VERY VERY slow going round! Now, as all the connections are fine, first thought was dodgy gauge! Bought a new gauge (needed a new bulb, new boost pipe anyway!), plumbed that in........ makes no difference, still the same!
Next thing was the t-piece??? maybe there was a blockage??? Spent some time today pulling it all apart, as its a bit awkward to get to on my car, i replaced the t-piece, put it all together again.... started the engine...... AND.... still the same!!!!

lol
Now, the only other thing i can think of is maybe theres a blockage in the pipe somewhere??? Daz mentioned it could be a kink........ doesn't look like thats the case after todays inspection!!!
The car still drives and boosts perfectly, so its not the car lol!!!
Any ideas??
