injector size (was Nother thought)

[Dave Zug]

They may have said that the actual pulse widths at idle would be greater
than the reported value. I'm curious what RPM do you idle at, and what are
the PW's at idle.  I have no experience with big injectors but I beleive in
the logic behind what someone may have told you. Hows the fuel mileage? Hows
emissions at idle? Otherwise?
