    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?

    I made 580 on c16, id1000s with 50 base pressure. 25psi. stock lines walbro 400

    on c16, id2000s walbroh 450 in tank with -8 feed -6 return, my buddys car made 785whp at 34 psi.

    my other friend with a built gsr motor running precision 1000cc, ran out of fuel on c16 at 27psi 630whp. we are thinking a good set of bosch injectors and he couldve been in the 700 territory
    2001 Boosted Built k20a2 Billet BB 6766BB

    2013=579whp 406trq @ 24 psi c16
