548 rwhp? I'm not a pro on this stuff, but that sounds like a stretch to me. What I would bet money on is no gains in that situation being contributed to the Alpina turbos. Lastly, even if the car did put down those numbers with the mods you mentioned, the original poster was probably hoping for daily driving power gains, not just when running race fuel.
