I don't see how.
The ECU calculates the fuel needed to reach the optimum mixture, and slight differences in fuel pressures will just lead to the ECU adjusting injector duration. It's not the fuel pressure that counts, but what the AMM, ECT and O2 sensor tell the ECU. The latter sensor closes the control-loop.
