I tried a lot of things regarding the hesitation and nothing really helps. Resetting the fuzzy logic of the gearbox control unit works best but it doesn't last for long.
The problem is well known, unfortunately customers don't seem to complaint about it because some think this is normal on a SUV (drive a ML55 or X5 4.4 dudes!!!) and some really don't care or even didn't notice it until I told them .
If Porsche wants to satisfy soccer moms and housewifes with this setup, fine. But I drive my Cayenne Turbo slightly different.

I'm curious how the powerkit Turbo setup will be: hesitation or not. I might be able to tell that soon.
