hmmmmm I'm interested in that. How much does it cost and what does it do to the performance / consumption. I think the only desirable improvement I could anticipate would be standing start like from lights at a motorway on ramp. Otherwise performance of the 540i is pretty good as is. I like that video on Youtube of a 540 chasing a Porsche 911 over the French Alps. The 911 couldn't get away although still too fast for the 540 to pass.
