Awesome mate thanks for the info.
I am running the 6758 which is the only 12 blade turbo in the EFR range so i could also use the divide by 8 function to get a better resolution.
150,000 (max RPM) * 12 = 1,800,000
1,800,000 / 60 = 30,000 Hz
30,000 / 8 = 3,750 Hz
3,750 / 8 = 468.75 Hz
Which is under the 'roundabout' limit of 500hz that the fury/extreme can handle.
