Yes it's just a standard HD. From what I understand there are two versions of the HD; One is noisey in some instances and one is not. The difference is in the number of fingers on the pressure plate or something like that... IIRC.
I have not spoken to the tuner about the exact numbers that were logged but i trust his advice. We will have another go after the front bar is sorted. Currently only about 5-10% of the core gets direct airflow and it's a real tight fit against oil cooler, aircon and radiator so it's tight in there at the moment. Without cutting a stupid amount of bar i should be able to open it up to about 70-80% of the core so that's a win.
