I don't believe so it's just a factory turbo model with factory scoop. I did a few searches and found that the 2010 wrx turbo only has 305hp, I think hes full of :q:q:q:q.
I didnt know the new WRX was that high. Thought only the STi made that much. The WRX used to only be 227 hp. Those are pretty easy to knock off, more so from a roll. I never ran an STi before though with my Mark. I ran a "380 all wheel horse power buddy" STi with my 03 Cobra and just destroyed him. He had me to about 20 MPH by a good ammount but after the wheels started to bite I shot past him. Of course the Cobra wasnt exactly stock.
