I'm interested in more discussion about the low pop pressure. What makes this happen? What advantage would there be to higher pop pressures? Mileage? How big is the trade off? By that I mean what do you gain in power and what do you have to give up? This goes against what I have been taught to believe about diesels. Why then does the Dmax run 30,000psi in the rail? I'm stupid, smarten me.
