You can't meet emissions without a proper 2000 bar fully functioning HPFP... I get that part. Therefore, yes, it would be an emissions violation by the manufacturer for your fuel rail pressure being too low to combust the fuel cleanly and properly. So if you see that P0087 code from your OBD II port, that is an emissions violation. :B If your vehicle stalls, pull the codes and log them down in ink, always, every single time, before it goes in to the stealership for repair.
Confirm that low fuel pressure (injection) will raise emissions, and cause it to fail the warranty.
The value proposition for high pressure injection is that the more spent on high pressure at the front end (fuel injection) the less spent on the tail end (after treatment).
Now, that is assuming everything stayed the same...
And it is not staying the same with the maintenance cost side of the equation.
