So what happens when you remove the Predator or are you running stock with this problem?

Found the problem injector feed tubes were out of torque range took back apart checked tubes retorqed with engine warm. If you change injectors you may want to retorque feed tubes after two heat cycles, or assemble with engine still warm.
