Cost me a grand as an exchange from Powerplay but it's a bit of a one off at the moment. Give them a call in a few weeks or about a month and mention my car (they know it).
Hunter - That does seem low. I had 162 with less boost. I have Nismo panel filter, CES split dump/front pipe, 3" cat, Fujitsubo cat back which is fairly quiet and an AVC-R for boost.
Just went out for a blat and turned the boost up to 1 bar just to see. Seemed to cope fine although the turbo seemed to be surging a little. I think that's because I don't know how to adjust the boost duty cycle on the AVC-R.
If you consistantly run 1 bar something in your turbo will let go so I'd stick to 0.85 if I were you.
