Riiiiiight feeling kinda stupid now.
I've found the issue, where the boost gauge hose T's into the FPR line, it was leaking air
Thought my vacuum was reading 0.7 instead of 1 - DOH
The car is now restored to post-turbo fitment performance. I have now idea what the FPR does but it obviously has a link with the turbo! I'll change the squashed pipe anyway as I've already bought it
