I got it from the original Ford training manual that describes the 3dr. It indeed says it has a soft rpm limiter at 6800 rpm and a hard limiter at 7000 rpm. But it also says the boost is gradually reduced to 0.3 bar above 6000 rpm or with ACT's above 70 °C. I suppose when coming from the Ford manual it should be correct. I also asked Stu from MSD what my 320 bhp chip does, and apparently that still switches the amalvalve at 6000 rpm and 70 °C ACT.
