One thing that occurred to me is that we tend to focus on the data from these dyno runs and base all our decisions on wide open throttle pulls rather than part throttle exceleration
or cruise . And in retrospect I realize that Frank spent quite a bit of time doing just this before we ever did a full pull .

I agree with how and what you did. But I wouldn’t do the one to the exclusion of the other. Another way to say this as bad as the numbers look (bsfc for one and it would nice to see the bsac numbers too) it would have been nice to spend some time cleaning up those numbers. I would have started by looking at the plugs after a wot pull and made some decisions based on that. I know dyno time is expensive and it flies by so fast you can’t believe it. I’m just a let’s clean it all up kind of guy. I don’t think a sacrifice needed to be made for cruise and part throttle or wot. I think that is where most of us are at. Just looking at the bsfc numbers means that somewhere there is power left, and I suspect it will show up in part throttle and cruise too.
