What fuel system were/are you running on the P1SC vette? I have an 04 Z06 with a p1sc and want to run E85 but don't know exactly what size injectors and what fuel pump to run. Thanks in advance!

Then post it all up here please.
I have the A and A P1sc-1 kit. a similar cam, 3.85 pulley (makes 11 psi with stock heads and intake), Cartek flip drive, Kooks 1 7/8 headers, 3 inch exhaust all the way to the tips, boost referenced return style fuel system with 255lph pump from the original A and A kit, with the racetronix hotwire kit. But i was only 532 rwhp and 479 rwtq. Each tuner has stated that i was running out of fuel. I assumed they meant that the system was inadequate rather than just injector pulse width being maxed out,(60lb injectors from kit)
Not complaining just want to maximize my system for now and plan on a forged engine, and better heads later on.

I get what you are saying. I was not saying that my parts are not adding up to what they should make.
I should have been more specific in my post. My first dyno session and tune was done many years ago with just the lingenfelter 255lph pump that came with the A and A procharger kit. The tuner stated then that I was running out of fuel at the top end. At that time it made 479 rwhp and 429 ftp of rwtq on 91 octane on the dyno
So years later I converted the fuel system over to a return style system with a boost referenced holley regulator, and installed the hotwire kit. But at the same time I added a boost friendly cam shaft, roller rockers, pushrods, 921 valve springs, kooks headers with catless 3 inch x pipe and 3 inch lg exhaust. This time it was tuned on 93 octane, as I moved back to NY from AZ. With the changes and octane improvement it made 532 rwhp and 479 ftlbs. I intend to push this little blower a bit more so I will need to add more fuel.
I should have asked my tuner whether he meant the injectors were maxed out or did he think it was fuel pressure or volume dropping off at the top end. I think the 340 lph pump would be better but I want to go even bigger than that so I wont be changing it out for a bigger one later.
