Thanks for the response. Wish I could load my graph. I only have a paper copy and no ability to scan right now.

One thing I'd like to add is info on air/fuel. It shows at about 15 from 2K to 3K and then tapers down to 12 by about 4.5K rpm. Is that normal?

I know, in general, there can be variations between dynos and even day to day, but just seems a bit low compared to some others I've seen online....and definitely from what Dinan reports.

Unfortunately I don't have a baseline to compare to.

Am considering sending the info to my SA to see if it is worth having Dinan take a look. I would expect a canned response, but no downside to asking.
