    question about injector pulse vs fuel pressure

    Just killing time since I'm not supposed to exert myself for a few days. Would higher fuel pressure and shorter pulse give better atomization? Same amount of fuel in shorter time.

    Yes increasing pressure would atomize tge fuel better but will alsi widen the spray pattern causing more fuel to hit the walls of the cylinder head.

    and your fuel pump may run out of "flow" quicker depending on boost pressures you decide on running because the more fuel pressure, the less flow it can deliver at higher pressures...
