I think the HPFP is most certainly the limitation at this point. Terry's logs show it cannot keep up with the demands, even with the Low pressure holding target perfectly. I wish we could get more information from Shiv on what they have done specifically on his car, we see the surge tank and the fuel pump, but have they tried replacing the fuel feed line with something larger from the LPFP to the inlet of the HPFP? Are they running higher than 72psi of fuel pressure on the low side?
