After reloading the stock tune file, The boost pressure dropped another lb to 18, throttle closed down for most of the run and the timing was sawtooth in pattern with slight knock. With my settings, we have the throttle open for most of the run and timing riding the cylinder pressure limit. Power feels about the same but the delivery seems smother and more deliberate with mine if that makes sense. Question, How long does it take to get used to these low timing numbers these operate at? I haven't touched timing at all yet but 0* is odd to look at
