i have check the pipes on the turbo and the are as follows

are the pipes the right way round?

there is a loud ssswwoooosshhh sound when i accellerate hard, possible air leek in front of the turbo?

could be why i am getting a reading of 1.5 BAR (this morning on the way to work) on the boost gauge just before the engine cuts the power?

heres a vid of the guage working, the second/third time i accelerate u can just make out the bang when the power is cut!

im going from 2nd - 3rd - 4th.

anyway heres a pic of the guage and the t piece connection!

the gauge does light up u just cant see it in this pic.

Assuming your running the std engine management, if so it has a cut off at 11psi iirc to save the engine.

You have probably piped up something wrong as the engine is trying to overboost

ye that's what im thinking it just finding what ones?? im going to replace the small 3mm sensor hoses the weekend for some silicone ones as when i push the oem ones on tight, turbo and sensor end it temporarily cures the prob until the engine warms up.
