If you meant, PSM (Porsche Stability Management) then:
When I was at the Porsche factory school at Barbour Motorsports Park in Georgia earlier this year, they had it in all the cars we drove and told us to leave it on. If the warning light on the dash flashed at us, we were doing something wrong.
At least on my '09, putting the car into Sport+ mode increases the thresholds before PSM takes effect. When I drove that car at SP, I left it on and liked it. Particularly good to have when it rains at the track - I do miss it on my 993 but only when it rains.
If you meant PASM (Porsche Active Suspension Management) then:
I agree with Vranko, skip it and upgrade the suspension.
