No the reason why it's pulling 255hp is because it has a better engine tune and a 3 stage intake manifold. I also believe it has a better exhaust but not 100% sure on that one. Although you can pull numbers better then that with a AA or Eurochagred tune, plus a performance exhaust, and a less restrictive intake (euro intake of bmw perf.), and of course a 3-stage intake manifold.
