Bit of a pointless thread really (no offence to you nickrsturbo1990), so many variables determine your BHP including rolling roads...... RR 'a' will say 250bhp and RR 'b' will say 190BHP whilst RR 'c' will say 225BHP.
Also as Chirstian says a Stage 2 T3 is only rated to about 220bhp (according to Turbo Technics and CR Turbo's) so anything over that and I would imagine the RR is being 'generous'.

I think all you need to know is that it will make good power and be lots of fun to drive mate!
But i'll still be interested to see your print out when it's been setup!

Good luck on the day mate!
