I said to myself, this is a Boxster, the mid engine should make the car very balanced and all, but it felt like an air cooled 911 when I got off the gas in corners.
So I put 4 more PSI in the fronts and it felt better. Then I went to 36 front and rear and now it feels great.
Is there a reason for 29 front/36 rear?

My best guess is ride comfort. The car feels smoother with 29F. I typically run 32 cold all around on the street.
Yes every car will exhibit throttle lift oversteer without active stability management... even a 63 Ford Falcon. It's a physics thing.
