I'm not sure, but I think the best thing to do would be to rig up a fuel pressure gauge temporarily (don't need anything fancy)
here's what you should check during cranking just to cover all the bases:
(1) do you have RPM signal in Megatune as soon as you crank the starter?
(2) Do you have battery voltage at each injector as soon as you crank the starter?
(3) Do you have consistent fuel pressure when you crank the starter?
On our car, the war (160 degree) cranking pulsewidth with 65 lb injectors was 3.7ms. If you have smaller injectors, this will go up to 4+ ms.
What cranking pulsewidth are you using?
