I have a MY99 with PPP and a K & N panel filter
On my last shot on the rollers (Well Lane)
my figures were 250 bhp and 242 lb/ft
Hope this helps

Well do you want real figures for how the car is all the time or to try to make them slightly higher so you can tell everyone down the pub how much power it has
Different rollers shouldn't make much difference. I was told that a group of Evo's went round the country, getting dyno's done at the leading rolling road places and the difference between them was neglible. They are all callibrated regularly, so should be much the same.
