sure can.. just wont be able to push enough fuel w/ high boost.

370cc - 35% = 240.5cc
370cc - 47% = 196.1cc
450cc - 35% = 292.5cc
450cc - 47% = 238.5cc


just different correction values.

Define high boost? 370cc injectors will work for 12psi. Your stock MAP sensor will fall out at ~10psi.

high boost meaning that at stock fuel pressures you will max out 370cc way before 450cc.

370cc will reach 100% duty cycle before 450cc..

but you cant rely on 100% realistically you chance fuel delivery at 90% duty cycle.

Duty cycle will be the same, but because 450cc injectors flow 17% more fuel than 370's, yes, he'll be able to run more boost on 450s at the same fuel pressure..

..but that was not his question..

Your MAP sensor will top out before you reach maximum duty cycle on 370cc injectors. Thus the reason for scaling with AFC. If you scaled 17% less than a 450 default setting of -32%@8000 RPMs (Which is what I have for 10psi on my personal setup), you're still only at -15% lean.. Still well within the 0% correction setting.
