    2004.5 Rail Hanging with 0% Throttle

    2004.5 Rebuilt with 03-04 pistons. Dual fuelers and 250% over injectors. Fleece dual fueler kit and controller. The truck randomly starts missing and smoking raw fuel. Acts like a bad injector. Looking at the log when it does this. The actual FCA duty cycle reads 1,600%, but mA will be 1500 or so. Let off the throttle and it stays at the same rpm and rail pressure. The truck lopes really bad and smokes really bad. Will also randomly start smoking and loping at an idle. Never seen the FCA duty cycle go this high as it is set at 71% max in the tune. Also if it was that high shouldn't the mA be 0.00? Can someone take a look at this log please?250% surging.hpl
