Hey BMW guy,its nice to see someone else bringing their own condoms just to be on the safe side trying to get a break form the board. While they are wearing your a$$ out they were leaving us alone for a change No harm done I hope just kidding some. There is no way 275 comes from a 44S in ITS trim. A good stock engine with tricked exhaust and intake should do very nicely in ITS. The rest is set up,data and driving. Data is worth far more than given credit on any car. Its not cheap either. HP loss through the drive train on the 44S is 20%. a few tricks can cut some of that off and its ITS legal but hard on the parts and short life through the tube. Fooling with the rear end of the car to bring it into the US can be changed and the back end stays put better. Looks like fun to me.
