400whp seems to be the max that the E90 N55 guys are seeing with FBO+e85.
RB Turbos and Vargas are both working on single turbo upgrades for the N55 motor that "should" be able to work with the F30 chassis, according to the vendors. I wouldn't be surprised at all to see 500whp with the turbo upgrade, that's what the N54 guys are getting with the RB turbo upgrade.
