To get a dedicated "boost" reading that doesn't involve me subtracting Baro pressure from MAP pressure I went into the math parameters and they have one already preset that does that calculation for you. I haven't driven it with that logging yet, but I was monitoring at idle and I was getting a negative psi reading in my graph.
