The N55 has all cast parts, which are not as strong as forged internals. This is the reason why almost every tuner only delivers (tunes) the N55 for 360 Hp vs 380 ~ 400+ Hp for the N54.

I thought so, its just been a while since I last looked into all that
Ill keep my N54 Thank you!!!
on another note I wonder why they chose to massively rework an N55 rather than the N54
