From my understanding the FD pump only gives about 15% leverage over the stock TII pump?

FD fuel pumps are not over 255LPH, walbros are good for a little over 400WHP on pump gas.

Upgrade your alternator and get a Supra pump if you feel you need more flow (they can pull 16A). I'm not a fan of the whine-bro if you can't tell. There are a lot of Chinese ones floating around, and the low pressure flow rate is just excessive.
