I'm leaning towards the tune and so is the tuner. Ecutek is being used, but the tuner doesn't have all that much experience with the combination of 370z FI and Ecutek, so I'm confident there's room for improvements in some areas of the map file.
But, yeah, I'll look into monitoring the fuel pressure during start-up.
