the purpose of this thread was to open discussions on the tuning potential of the N55's valvetronic system specifically (hopefully with the input from some of the tuners).

so according to BMW, the valvetronic system is supposed to increase fuel efficiency and performance at the same time. based on a number of reviews, this system also makes the engine run smoother.

my question is, can N55 tuning to the valvetronic system provide any additional power? or is this primarily geared toward fuel efficiency? my guess (based on zero factual knowledge), is that tuning valvetronic will provide little or no gains but i really hope i am wrong.

if it is possible to tune the valvetronic system for more power, lets have a discussion on how it works and how it can be improved for power.
