Be realistic about the size of this step: roughly 6% more power, won through ignition timing, fuelling, throttle mapping and rev limits, because there is no boost to raise. Porsche calibrated this engine tightly and it revs to 8,400 rpm from the factory — there is less margin here than on almost anything else in the range.
