RE: Dyno tune...finally

One thing that surprised me was that power dropped off after 5,400rpm, which was about 400 lower than I was expecting. To make a better case for the necessity of a tune, look at RunFile_001. That was a baseline pull before any tuning was done. Little difference?

That's the one. The runs are printed out on the sheet 2,3,1 from top to bottom. One one hand my timing was pretty retarded at that point, but ~65hp is a pretty big difference either way

Good numbers. My final results were very close to yours. I was a little lean about 14:1 when I came in for the baseline. However I only needed a fuel press. adjustment to correct things and that was it.
