Peak boost will do.
I may very well be gravely mistaken, but I doubt many of these piggy backs alter the boost ramp rate (partial wastegate actuation), and just alter peak boost targets, and let the ECU figure out how to get there fastest as per factory tuning.
I've only read of one piggyback that has altered the boost curve to lower boost at lower RPM.
