With proper tuning you should see around a 50rwkW delta with RBs over stock turbos, more if you tune for "kill mode" with RBs.
However the peak power figure doesn't tell the whole story, as they hold power to redline far better than OEM turbos and are also capable of significantly more midrange torque if tuned accordingly.
Attached is a pre & post dyno overlay of a RB customer from Melbourne. Whilst the results are very good indeed, given that he is running E60 he has left a few kilowatts on the table as boost taper between 4,500rpm and 6,000rpm could be less aggressive.
