TQ managment?

Does anyone happen to know if fuel flow is involved?

As in, if fuel flow is reduced so will TQ. As RPM increases so does air flow and fuel flow. If the pump hits a flow limit (software related, amp draw?) then to hold AFR stable (as commanded) will the TQ management reduce power?

I ask because:



and with a bit of very rough math,
It would seem like the limit of the stock LPFP for a Gasoline BSFC would be around 400HP.
So can I say that for anyone running more than Gasoline (higher BSFC) you'd need pump upgrades?
