RD Sport is anticipating 620hp (crank probably). I'd say that's very optimistic. I'll go with 590hp (crank) with DPs, IC, exhaust, and tune.
Its not a gt mustang,full boltons wont only yield 40 hp especially in a turbo powered bmw. Look at the n54 335i for $349 you gain 100 hp. It might take some time but i do see the 550 hitting 700+ hp with just bolt ons.
