You can adjust the preload on the actuators to whatever you want, i was just just saying that with a stock 993tt the actuators are set to open 4mm at 0.5bar. This is what the motronic ECU needs for correct control over the wastegates, you can add a little more preload and keep the wastegates closed for longer.
What ECU are you going to use for your engine?

Some good reading on wastegate settings with Motronic, Kevin from UMW explains quite a bit
