It is unlikely that the N55 will be able to achieve such safe increases of 60bhp just via a plug & play system like the N54 was, so an easy way to remove any internal competition. Doesn’t help either that the ECU is now relocated behind the throttle body, in the variable heat/wet conditions piggy back boxes wont have an easy time. But then again maybe that’s just a side effect since the N55 should still deliver 7-8% better economy which can only be seen as good since it delivers close to identical performance from the factory. Combine with better throttle response I think most will be happy that progress.
