This is a great Porsche to own if you can find one. The sound is fine if you keep it above 3000 RPM. No turbo lag, again if you keep it above 3000 RPM. I am still in the "running-in" mode until 2000 miles are on the clock, so it will be awhile before I can give a more complete evaluation. I do like the PASM. With a little care, the lower ground clearance has been no problem. I haven't seen anything above 17 psi on the boost gauge except for one unintentional run to 5000 RPM when my enthusiasm got the best of me.
