Interesting Benny. I have the BP gauge and I'm about 18-20 on idle and 45-50 running hard. I've yet to see it at full tilt, might be because I'm kinda looking at where I am going!
I have the temp gauge too and I believe it's giving more the case temp than the oil. Still like it better than the stock filler cap. Here in South Florida, I run 200-240 regularly. Last year in NC, I never topped 180.
