Who applies more boost after full spool (which implies it hasn't reached full spool yet)? When boost should be taping off after that point. Tell you the truth, something is not right with your tuner's logic.

Also, the EJ207 doesn't have rod issues where you need to limit torque. The proper tune would be to give it as much boost as it'll take as early as possible without knock and then taper off when it's no longer making power at that boost/rpm level.
