    So would this mean putting over 60-65% of fuel in hat would be better?

    This is where guys say higher pressures are more responsive to tuning. 200psi at 8000 rpm. right?

    Depends how you tune a motor. Pretty well the standard is 125-130 psi at the pump output at 8000 rpm in first gear. With that I don't worry about what it is elsewhere in the run
