Is it more reliable to run a way larger than nessescary injector at a lower duty cycle then a small more suitable size at a higher duty cycle?

..what the hell kind of answer is that?

anyway.. it's smart to try to keep duty cycle under about 80%. I usually size for about 70-80% max if I can. Too big though, and you'll have idle problems. It's difficult for a large injector to flow a small amount of fuel like at idle.
