The reason to have a minimum pulse is due to injector latency. If you could force it to run below 100us, the injector wouldn't even inject fuel, not enough time for the pintle to lift before the solenoid shuts off again.

I agree with using a stock pulse table to start with, but you do need to reference the injector flow sheets. This will give you an idea of how much to cut in the low mm3 / mpa areas. If you don't have this info, reference what mm3 a stock truck idles at, then log what pulse your truck idles at and apply that pulse to the stock idle areas and blend it out to the rest of the table.

Remember, a 150% injector only flows that much extra at full rail pressure, so you may only need to cut 20% or so like was said before. To keep a minimum duration in the table, simply subract 160us from the table (if this is really the minimum duration required), make your desired changes, then add the 160us back in when done.
