I have Kodiak 4500 with LLY, I started getting 1093 with truck and trailer at 31,000# with Edge set on 2. Then it started getting worse throwing them stock empty around town. I plugged in my Predator and was able to monitor Desired fuel rail pressure, and Actual fuel rail pressure. When you would floor it you could see I was starving for fuel. Change fuel filter and both numbers stay the same flooring it on Level 5 empty.
