I left the min/max tables untouched. I considered the PW size difference, but regardless, PI should have followed DI, not jumped all over the place. Try making all three tables all zeroes except for a line of 20% down the right side and across the bottom. Drive and log that. Tell me if it does it to your car as well. When I zeroed out the whole tables it turned off PI completely, except for idle. At idle it came on some of the time.
(edit) Could the PI pulse width have been magnified by the manifold pressure? Since I have the Phantom SC with the Procede controller it was on and boosting when the PI was jumping around. Could the PI have been using more PW to compensate for pressure in the manifold?
