I figured fuel pressure is just a constant that any tune is based around; not a variable that is incorporated into a tune. Is that correct?
The tune is a Specialty Z EPROM that Greg put together for me when I bought the EXP90 kit. I assume it should be just about the best tune I could get without having a legit pro-tune done. I assume the pulse widths are correct, but 45psi on a pulse width will flow more fuel than 35psi on the same pulse, right?
