PSM increasing braking distances?

Just got an '03 boxster S with PSM. Only made it to one DE and left the PSM on the whole time. I felt it kick in a few times, nothing too obtrusive.

What I did notice was an increase in braking distance. Not all the time, but enough to scare me a couple times. (I guess 911s just can't go as deep as me)

My '02 without PSM only did that when the brakes needed to be bled, and the pedal got long.

When the '03 S braking distances got longer, the pedal did not get long.

Whenever I notice the braking distance is long (feels like I'm not getting enough pressure on the pedal) I switch off PSM and try another hard braking, then it feels ok. Then I switch on PSM and try it. Always feels ok.

Anyone ever hear of or experience that?
