I agree about ditching the FMU. You don't need it. Throw it away, far far away. If you're running underdrive pulleys, toss them as well. You can't run underdrives with a blower...the pulleys will spin the blower slower which (I'm pretty sure) isn't what you want
. You should be ok with the 30# injectors and a 255 lph fuel pump. Just set the timing at 10* and FP to 40-42 psi as a baseline and tune it from there.
A dynotune and custom chip would be a good idea in the future.
