I suspect there is not a lot of tuning potential in the N55 and that is why there are no wothwhile tunes out there for this motor. I have always said BMW downgraded when they replaced the N54 with the N55. The N54 spanks the N55 all day long and I wish I could have lifted the 80k miles old N54 out of my 2008 535 and dropped it into my 2011 535.
