Thanks for all the advice, the problem turned out to be caused for 2
reasons:

1. The fuel pump was on the low side, but it turned out to be only about 1/5
turn out.
2. Whilst getting desparate, decided to clean out the intercooler, and found
that there was a 2" slit in the hose from the turbo to the intercooler, it
must of only been running on 1psi boost at the most.

The thing is now as fast as the Disco was, what a difference.
