trying to wrap my head around if my tune is messed up or if adding this pump (x2 dw400) was originally get fuel codes, which have been turned off since.
with the same tune as before the pump the car now goes from lean to rich to lean again under light load. Car acts like its chocking.

1st pump currently has straight power with the OEM pump control wire(grey) second pump is boost reference with the aux pump.

port is firing when commanded

fuel pressure shows around 70psi on the log the during all of this.
