06 gto dyno numbers?

[06_goat]

Hey guys I just bought my first goat a couple of days ago it's an 06 M6 with Texas speed longtubes, Corsa extreme catback, verram intake and a tune. I raced a friend of mine last night who's car makes just shy of 400rwhp and I beat him, can anyone help me make sense of this?

I didn't think they offer the exteme for our cars. Only sport and touring...
