pump is on or its off.

so at high boost/rpm, it will be pumping in what the wi injector is designed to pump in.

whether or not it is progressive.

so there wont be a too much too low, not enough up high, because up high is based on the pump and injector size.

is progressive better, maybe, but i dont have mine turn on till like near 1bar.

if im at wot, i want it on, and given spool time, going from for example 7-15psi on a progressive is instant anyway, so a progressive for me is pointless.

unless your progressive is based on rpm with an ECU?
if its based on boost, to be fair, most turbos are instant in the boost you see.
