If you can get a 2 step/WOT box wired into your car or if its part of the ecu you are using it will help your launches and also spool the turbos to max boost on the line.
I've been drag racing my whole life. (not Porsches, mostly mustangs) but the concepts are the same.
My last turbo mustang I built picked up .7 in the 1/4 mile, when I wired in the 2 step and found the sweet spot on the launch between hooking up, bogging and murdering the tires with spin.
