BMW B48B20 Engine

The power curve of the BMW 2 litre engine.  I have often thought that this engine would be good for aircraft.  What do you think about the odd power vs rpm curve? BMW are limiting output to increase as models evolve. I have found how to add 60hp to output very simply.

I guess that a new chip would increase the output.  But the Bosch engine control module must be encoded some difficult way.  There are several kits to add the 60hp max increase at the moment.  From what I can see all halve the manifold pressure to the Bosch unit, it then increases the boost.  Mmmmmmm.  But what a trick BMW is doing.
