What inline pump are you using? What ethanol percent for 606 whp?

I am running a Fuel-It stage 2 pump, Fuel-It TBI, Hexon RR600s with 20psi with E65 and am guessing I am at ~550whp. The low pressure is crashing above 6200rpm and am looking for options to improve fueling. Any help is greatly appreciated.

Also, I ran 150.2mph at WannaGoFast 1/2 mile from a dig.
yes.

ethanol was probably E60-70ish? i had a few gallons of 91 oct + E85, but i have no idea if it was actually E85 from the pump.
