Fuel Pressure Tables And Dual Fuelers

Hello,

I am currently getting 12k rail pressure at idle on basically a stock tune with ats dual fuelers. I was curious, when you have dual fuelers do I need to cut this tables in half to get the desired idle rail pressure?

Ats dual fuelers with controller box (all new)
duramax 2nd pump, new and duramax fca (does this need to be cummins?)
lift pump pressure at the engine is 8psi (12psi throws p0088 rail pressure too high)
white smoke from tailpipe
rough idle, lots of injector knock


Thanks in advance

Did you ever figure this out?
