So managed to get get into the workshop this morning for a few hours to find a boost leak, nice being a Refrigeration Engineer, as I have access to certain equipment.
I used a small liquid line refrigeration drier to form a plug/bung with 1/4" fitting and then clamped it down.
I left that hose connected, just adjusted the angle:
Blanked off this end (that connects to the outlet of the turbo)
Gave it the beans:
But... I couldn't put the nitro in fast enough! I didn't manage to get a photo, but did take a video of it, its the lower aluminium elbow that is pissing out.

They all held great. So going to buy an after-market inter-cooler in the next few days.
Thanks for all the help guys!
Matt.
