on my red , it's 4.0 and 38% duty , boost " A " is a constant 20.6 . What I figured out is reduce your crack pressure it reduces spike but causes more lag , so what I did was reduce the crack to 3.0 and duty to 30 then slowly increased the crack by .5 and the duty by (2) untill i got the # I was looking for. Once your hitting stable boost then increase the WG duty cycle only to achieve target boost
