Just trawling through SAU and forum sponsor CRD's page - and although they refer to accessport tuning for R35s I'm sure they can manage a lowly MPS?
You Sydney guys should follow it up.
For those who don't know the shop, google their GT-Rs - Cant remember the plates on their 1200hp R33 but the r34 had 'RH9' for a reason!
