yesterday i was driving along and all the sudden at the stop sign i looked back and the whole street was a wall of white smoke. what could this be? im between an egr cooler, head gaskets or something as a bad fuel filter. before it did this i was doing some tuning on the truck, the injector balance rates were just fine. the worst one was -2. half the time in my big tune it would get good fuel and smoke and spool great, then a few times it would take off moderate with no smoke and didnt have much get up like it was startving for fuel. any help is appreciated, thanks! if you can text me with details shoot me a text at 217-248-8116
