Will be interesting to see where we end up. With port, we no longer have to run high low side pressures to overcome the flow losses at the inlet of the DI pump. As we lower the low side pressure, the in-tank pump will move more fuel volume. We normally drop the commanded low side from about 70+psi to about 50psi as injector flow capacity is no longer an issue. That, along with the JMS, hopefully will allow Greg to get away with the expected 10 psi from the 105mm pulley.
