Cheers Dazza, the line on the throttle body I connected it to originally was the correct line and should have worked. After talking to a few guys on ozdat who have connected it up the same way their is no reason why it should not work.

Cant get car out of shed at moment to take it for a spin to try it again.

After bit of reading its a pretty big risk to splice into FPR line, so will leave that one alone. At the end of the day it may even be a sick turbo, appears to be leaking oil into intercooling piping again.
