Any other information.....boost gauge , ECU, UK mods, because to me it sounds like your not making any boost, perhaps you'd like to try the single turbo forum.

Sounds like a massive vaccum leak under boost. check your couplers for your FMIC piping. My TII was doing the same thing until I checked and tightened down all my t-bolt clamps. Fixed the problem right up.
