800+hp fuel system?

625/460 id2000 54% duty. 50 psi base

Recently, people have been fussing online about duty cycles being too low by running too large of an injector. At 54% duty cycle, do you notice any issues at all? part vs whole throttle, start-up, etc?

I think it has something to do with fine tuning the setup. But it's probably worth it if you're planning bigger stuff later on. Used injectors go for cheap online, idt it's worth the money loss. Eh.

Merry Christmas guys! (belated)
As for the large injectors, low pulsewidth response get worse as injector size increases. It's like using a firehose to fill a cup. But the extent is variable. For example: Using 2200cc set on a 300-350whp GReddy kit. Nah' mean?
