I'd be curious to see actual dyno of this vs. Cobb, or others, on the N54 or N55, since speculation and many dyno runs seem to indicate that 300 HP is a conservative number, even for the N55. So, if BMW is adding 20 (or is that conservative too?) to their already conservative number, and Cobb is giving their best dyno numbers...
