[A Majority of One]

Tomorrow I'm trading in my 2011 550 for a 2013. I'm assuming this power increase is entirely just a change in the mapping for the engine. If that's true then I'm assuming that it's an irrelevant change if I wanted the stage 3 from Dinan. Meaning the current stage 3 would still work just the same and have the same end result as it does on the 400hp 550s. Can anyone confirm this?
