Would there be anything gained from using a different in tank pump in conjunction with the larger aux? Im currently running an lt4 in tank pump.

Aux setups will cavitate on road course unless you keep them above 1/2 tank. My brothers Z06 makes north of 1000whp with LT4/JMS and DSX Aux with upgraded pump. Low side holds fine on E60. Haven't tried more because the LPE high side pump is maxed.
The Katech dual drop in pump would be the solution for road course if you want to be able to run below 1/2 tank safely, but we don't know the actual limits of what it will support. Manufacturer claims 900whp on E85 but haven't seen it firsthand.
