I was just mentioning that DI systems run at least 3x the amount of traditional fuel injection systems.

If the N54 does indeed run about 3000 PSI of fuel pressure, then in my opinion, I would tune the car to about 13.0 AFR to about 13.7. I cant make a definitive claim on that, but based on my experiences, it would work.
