Funny, before I got my 550 I was thinking of SuperCharging my old 530. However, that was a 2005 530 (M54 engine) that had more mod possibilities, such as ESS and VF engineering. The 2006-07 530's (N52 engine) don't have a lot of modding possibilities. Sorry Bro, never heard of anyone turbo'ing that 530.
