That sounds like the tip!
However, it is a pretty smart transmission (I actually love the Tip). It will "learn" your driving style (for the duration of the current trip) and will adapt the gear changes accordingly.
The only way to truly override the "too quick" gear changes is to put it in manual mode and hit 55 in 3rd
I DO wish there was some way Porsche (or aftermarket) would allow re-mapping of the "templates" in the transmission and allow for higher RPM changes between the gears while in Auto mode. Anyone know if that's possible with the PST2?
