I found a random advertisement on the GM 0280156086 for 213cc/min at 3-bar pressure, but I don't trust it as other info they had was incorrect. I would suggest measuring timed flow with your pump and regulator into a container for a general flow measurement. You just need to know it is reasonable for initial calculations, and you can adjust from there once running. Or, if your pressure is the same, just try 213 and you'll find out. There are times when math helps, and other times you just have to find out for yourself.
Keep in-mind that Req_fuel can be inaccurate based on the info you enter. If the info is wrong, you'll find that quickly, with overall rich or lean to some small or large degree. No big deal, as you can then use Req_fuel as a sort of "fuel knob" to dial your warmed running into the AFR target area. This manipulation brings R_f to match your calculated VE Table, rather than working the table to match calculated R_f. Neither value may be correct, but you can find the truth as your tuning progresses.
