They might be expensive but they are actually upgrading the turbos (bigger compressor wheels?) so it should theoretically have the ability to produce more power than just a tune. I am not sure how many options are out there for the 550.
Well the weather should be very favorable this weekend and it would be interesting to see an M5 run on the same day in the same conditions. I think 119mph might be a bit optimistic but then again you might get there if you can run high boost on race gas in perfect conditions.
