Oh, and additionaly there si still the option for a higher pressure DI pump version, which is common to be done in motorsport enignes (e.g. WRC, WTCC).
The stock system finishes at 16 MPa (=160 bar) as the relief valve is opening at that pressure.

Rising the pressure to at least 20 MPa (200 bar) would give substantial benefits in flow rate AND mixture generation => better knock resistance, faster flame expansion, better charge cooling inside cylinder (more filling, less knock)

But thatīs some far-uture stuff, surely nothing to happen within 2015.
