I'm going to guess here (hope no one minds) but they don't want the
injector to ever hit 85% (open) pulsewidths, because as they age they can
get "stuck" open.  By using larger injectors, they can keep the pulse width
down to say, 65% at WOT and everything will be reliable.  At least during
warranty <Grin>\
