I found out some very interesting info on this today. I need a high HP car to test it on and the 1 I have been tuning switched back to 93 so that's no good

I'm doing some more research but did learn a few things. May have a new pump to try

I remember reading that the new hpfp cars move more fuel but the hpfp cannot be fit to our cars. something about our hpfp being configured for 3 lobes and the new cars having 4 and the ecu cant read it. maybe I misread.
also, I saw the gmtech posted that you can modify the in tank fuel pump to increase base fuel pressure which helps feed the hpfp. you smash the 'hat' on the fuel pump to increase fuel pressure. someone did a write up on hp tuners.
thinking along those lines, couldn't someone get a bigger fuel pump and an adjustable fuel pressure regulator and increase the base fuel pressure which would then help keep the hpfp pressurized more?

I'm sorry but the info I have provided is fact backed up by logging many different cars on different setups. Opels lower pressure on 450hp+ cars

Yes. What the stupid thing is about this whole thing is ZZP doesn't say anything. What's the issue with telling us that they have 1 that they're testing how well it's doing and a ETA about the next update? The way the develop new products now is terrible. Didn't they post info about testing when the original ZFR was being developed?

I was curious so I checked out my dyno log. I was on stock injectors, lobe, E30 and around 900cc 80% meth. That came out to 511hp with an IPW under 5.5ms!

Yeah that is the one we've been putting on the board for 8-10 months. It had to be modified to work fit, but we are compiling data to be able to make something work! I've been driving that **** out of car with lots of logging and different setting and the like.
