Ive searched and found a few hits regarding the PSM kicking in a touch early but wondering if any other 997TT owners have experienced it.

Essentially mine only kicks in on sweeping left hand turns, nothing crazy, think freeway ramps, 65-80- mph or so and its happened in all gears across all rpms (I tried it).

It feels like the back end suddenly tries to stop itself, feels like one side of the rear brake kicks in for a split second, sometimes I catch the light flashing on the dash.

I was not pushing the car hard and other vehicles were doing the same speed or more. Oddly Ive only noticed this now I just had a new set of rear tires installed, same Pirelli's as stock.

Did the checks, sway bar fine, tire pressure fine etc. Thoughts?
