I looked inside the program and found that pulse was back on and injection timing was set closer to a qsk engine than a highway truck as well but had a curve in it for fuel mileage in lower to mid torque areas. One thing that I had to wrap my head around though is that some of the smoothing was achieved by lowering rail pressure slightly and making up for it by increasing fuel through the air-fuel-ratio settings instead. Makes for a slightly longer burn on the fuel making expansion not so sudden, harsh, and rapid on consecutive pulses. I think it even increases the power stroke slightly because of this due to it having a more consistent burn between pulses. The one I test drove seemed to respond better than I expected for a 575. The other guy I was with said "d@#mn this thing will get you a speeding ticket fast!". lol. It was definitely not lazy at all.
