I cant remember if your dyno graph showed the typical K&N drop in torque at around 2000-3000revs but Chris has started testing the prototype filter using the PC5/AT and he reckons there is no apparent dip in torque anywhere, only his butt dyno at the moment.
Ramair have already arranged for Wayne Tripp to have a filter to test and they are trying to get Nev Lush on board as well, that's why I asked for his email address.
Hopefully they will both take the filter on so that you 'foreigners' can get hold of them easily. Having said that Ramair deliver to anywhere in the world for £9.50.
