That’s a good starting point. Next, manually calibrate dynamic flow. Finally—as @hotellonely noted—keep the filament thoroughly dry and slow the print down; support materials can be unforgiving.
As a side note, consider Support for PA/PET. In my experience it adheres very aggressively: if not removed promptly, it can bond to the model; it also tends to ooze and leave debris across the build plate. It does, however, support the model reliably—arguably its only advantage.
