Actually Stock 550i were dyno at 380 wheel hp. So you are pretty much stock.
You should get it check out.

People making assumptions by looking at the absolute numbers only have no idea what they are talking about.
Thank you Alextremo, Smash is hung up on stock dyno numbers without realizing that dynos vary and the main reason for a dyno is to calculate your gains.
