Apologies - posted this first incorrectly in the 'turbo' board.

Put about 100 miles on the X51 Cab. Just getting the running gear seated and worn in a bit. I've had two 997S cars already, a coupe and a cab, and this engine feels markedly different. It feels freer-revving and stronger - to those with a broken in, sport chrono "S" car, the powerkit option without "sport" engaged is what yours feels like, in the sweet spot of the powerband, with "sport" engaged. In "sport" mode the X51 is really special. All around, the engine has a good bit more oomph. I am looking forward to the end of break-in on this new one. The PASM also seems better - the 'wobble' - for lack of a better term - with PASM on sport, in a corner, although never really pronounced in the other cars, feels nearly absent.
