Update: just took it for a short rip after installing the M Perf shift knob. Can confirm 0 lag between shifts, and monintoring the boost I can see the wastegate seems to be closed during off-throttle, still making about .2-.4 bars of boost off throttle in sport/sport+ around 4K RPM.
Shifting through the gears is instant power response 0 lag at all. Top peak boost I saw in 70F ambient and about 35C IAT was 1.2X bar. Which is just over 17-18psi..
