I think it depends on the driving involved. If you're autocrossing, you
*have* to bump up the tire pressures, especially in the front. This
prevents some sidewall rollover, and as such should improve response in
hard transient maneuvers like a slalom. One might argue that this
reduces understeer too, since it keeps tread on the course and not
sidewall.
On the street though, overinflating a pair of tires reduces grip from
that end of the car...the tread surface "ballons" a bit so there's less
contact patch.
just my 0.02...
