I got the scan gauge and hooked it up for a quick test. It's a pretty neat device, but I need to read all of the instructions. I have not figured out how to get data logging to work, so I had my daughter video one run on 80DD up to 65mph or so. Looking at the numbers, I am wondering if I do have a weak pump, but not sure what I am really looking for yet. I want to do more runs on the 100HP setting, but just have not had a chance yet. Here is a link to the video. Interested in what you guys think.

In case the video does not work for you, here is a plot.
