I am running stock dual Bosch pump in series on config. The rear pump is new. I am using ID725cc injectors and the max duty cycle I saw is ~48%.

To be clear, the FPR seems to be doing its job - pressure rises as boost builds; to about ~60psi. But, It doesn't rise about that nor can it stay flat. Fuel pressure starts to drop by the time RPM reaches ~4200.

I'll post a picture of the data log shortly.
