I turn mine off every time I drive the car.

The Best Motoring video shows they got a faster lap time with the PSM on. It has nothing to do with HP, its all about grip. I had a C5 Corvette for several years, and their active handling system is much more intrusive than the psm.....it actually kicks your foot off the accelerator. Thats why better Corvette drivers switch it off. The psm is much better.

How can you say you have full power during wheelspin? Thats why Vipers so routinely get beaten by cars with less hp.....the chassis can't handle 500 hp.
What the mechanic is saying is that when a wheel starts spinning, the psm will damper the force applied to that wheel. Using psm provides you with greater usable power as applied to the asphalt.
I find that psm coupled with variable AWD makes this the best high hp platform in the world. A 600 hp 996TT would wipe the floor with a similar hp Lambo, Z06, Viper, Ferrari, or whatever on a track

I like the cut of your jib, sir! Gives me hope and a warm fuzzy feeling of great joy and pride that my baby of 548 BHP can still give performance cars of newer generations a run for their money. Thank you for the pleasant Thanks Giving gift!
Happy Thanks Giving to all on this board!
PS. Wish those in New Orleans a happy thanks giving as well.

Again, this is different than the Corvette where your foot is pushed off the accelerator, which would reduce hp by reducing revs.

"The events below inform the driver of PSM control operations" Several events are listed, and one of them is... "reduced engine power."
"Sophisticated sensors poll the ABS, anti-slip regulation and automatic break differential systems for data on speed, wheel rotation, steering angle, yaw and lateral acceleration. In an instant PSM uses these values to calculate your cornering line and correct traction loss by discreetly applying brake pressure to individual wheels. If necessary, engine output is also regulated."

This information is from PCNA...
PSM is not only a braking system. If you lift off the throttle in a low traction situation and the back of the car gets loose, PSM will increase the engine speed (blip the throttle) to keep the car in line. Also, if traction is low, PSM can use engine braking (EDC – engine drag torque control) to slow the car. PSM can calculate the amount of available traction by comparing wheel speeds at all four corners of the car.
Now back to my pie...

Wheel speed sensors tell the car when there is wheel spin occuring. It does limit engine power.

If thats true, it must be a last ditch going over the side of the cliff interlock 
I haven't had it kick back on me, where as the Corvette was always doing it. Going back to the original question, psm does not take away useable power on a regular basis. Mmmmmm...chocolate pecan pie
