Not too surprising.  With lots of boost in the manifold there's no
vacuum for the brake booster, so once you use up the vacuum in the
reservoir you're down to whatever pressure you can generate with your
foot.  So you just have to push harder. :)

The brakes are capable of generating way more torque than the motor
is.  After all, you can lock all four wheels with the pedal pretty
easily (or at least you could if the ABS were disabled), but can you
spin all four of them with the motor?  Maybe in 1st with a chip and
K04s, but you certainly can't do that stock.
