I don't have an N55, so I can't help you specifically.
What I did with my B58 was to enter the car's transmission and differential ratios into a gearing calculator. I then looked at where the RPM drop would leave me on Dinan's dyno graph for the stock engine. I came up with 6000 RPM for my shift point. I then confirmed that number with a BMW race shop.
