Does below represent your fuel system?

Tank with stock pump to Y
line 1 to HPFP
line 2 to inline pump to PI

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.
