Made a post before this about the issue, so with a 5 month old FPR, brand new LPFP from fcp euro, new HPFP from fcp euro, non leaky injectors, new injector seals, 6 month old lpfp sensor, and now I swapped my ekpm2 out for a ekpm3 and coded it.. the same ISSUE still consists. I’m attaching the data log. I got the Cylinder injection cutout code. Half engine light. I’m on MHD STAGE2+ FBO, e30 but even happens on 93 octane. Should I just replace everything again? Like dang it dude. And no fuel leaks either or smell.

Something is fucked up with the install. It's only making 50psi at cruise when it should always be 72.5.

I'd be suspicious of the regulator or the connections in the fuel tank to the pump.
