I took delivery a week ago, installed MPE 2 days afterwards.
As I drove home from the dealership, I didn't feel the extra juice provided by the PPK (based upon what I remember driving a non PPK on test drive). But, as the days and miles passed, I certainly felt the added power. As others have claimed, the ECU either adapts to one's aggressive driving style or gets "broken in". The roll-on punch it provides is awesome. I don't hammer it off the line as the car is still in its virgin stage but, I sense that experience will also be awesome when the time comes. Throttle response is immediate; turbo spool is audible. The deep, understated tone of the exhaust is a nice addition.
