In either case both would be a 335Xi M-sport packages.
From a little research it is obvious that the N54 motors have a lot more tuning potential, just looking at the accessport dyno's the difference is unreal. Definitely is a mod that i will be doing on what ever model i get.
There really aren't any significant tunes for the F30's N55 yet - the DME is different than that of the earlier N55 cars (pre-2013). There's a PPK from BMW due out in March, and without a doubt we'll see something from Cobb, Burger, Dinan, and maybe Procede, but probably not for awhile yet. The J55 from Burger is available now, but will undoubtedly be superseded by a new JB with significantly more power.
