leon cupra 300 official bhp?

Hi im new to seat ownership having just taken out a 2 year lease on a 5 door leon cupra 300 dsg and ive got to say first thoughts im very impressed with the car and the performance is better then i thought.My previous car was a bmw e46 m3 so a completly different car all together but i actualy think once you have got the leon off the line it feels faster then the m3 which had 343 bhp so im quite shocked.Has anyone actualy done a dyno test on one yet?

thanks mark
