Is it bad to run high fuel pressures constantly? For example around 60 psi at idle? I'm using a walbro 255 lph pump. I will be using a s-afc to turn down the injector cycle duty. So basicly, i lower the injectors alot, then increase the flow by rising the fuel pressure. thanks.

as long as it doesn't exceed the pumps limits, i dont' see any problems.

 

those walbros usually start failing at 100psi plus...

 

The pump will run hotter and draw more current, but it will work.
