Injector size

Ok, i bought a apexi pfc, and 750/1680 injs. I installed the 1680s but need the 750`s rebuilt. I have a rtek 1.7 and a safcII temporarly. Can i turn the 1680`s down to 1000cc... My calculation is 1680 x .41 (-41%) would put me at 991cc . My question is i ran 720/890s before and maxed the 890 duty cycle out wBnr stage 3. I have the 550/1680 in right now. I also have the timing ret. -2 degrees.

My mods-
FMIC
MBC
aem wideband
deadbolt s5 hybrid ( similar to Bnr stage 3)
fuel pump rewire
supra TT pump
3" rb exhaust
retk 1.7
safc II
