I understand the PPK for those wanting to keep their cars original in all respects, but other tunes release so much more power and don't seem to give any issues if set at recommended settings.
The one appealing point of the kit is the the stage 2 added cooling. BMW came VERY short on effective oil/water cooling on these cars.

Not sure about the HP gain, but I am fairly certain the torque gains are more than the 17 ft lbs states. The car has MUCH more torque with this tune, no doubt about it.
Bear in mind that part of BMW's marketing strategy with this SW only kit is to retain would be buyers of 1M's that can't get their hands on a car. Easier to sell them on a moderately priced, upfitted 135i in theory.
