First of all, this is a public forum so you're the one that can go fly a kite if you don't like my responses or think they are not what you want to hear. I am not flaming your setup I am trying to educate you.
Second of all, I am helping you. I'm helping you get your setup sorted. 24#/hr injectors are too small and of story.
Using an FMU is something you did in the early 2000's when you didn't always have a programmable ECU.
But you do in fact have an ECU that you can program so using an FMU is stupid, no if's and's or but's about it. Put back the 1:1 regulator and buy bigger injectors.
That you cannot get support for something you bought 2nd hand is a completely separate issue.
