A 12:1 disk would work but to keep fuel pressures down you might want to look into running a 10:1.

Have you looked into running the afc-hack by any chance?

so the 12:1 would work better but the 10:1 will keep it from running rich at idle

i would say 8:1. 10:1 and 12:1 is too much with those injectors.

with 370cc injectors you would probably want to run the 6:1 or 8:1 FMU
