i had done a cam swap on the dyno in an RPM headed 446.
What the real results of the cam swap were, was basically the opposite of what the DD predicted.
Said the new cam would make less...... but it made more.

Ever use PipeMax? I never have, because I went to a Mac years and years ago, and Larry’s stuff doesn’t work with a Mac.

I suspect that is about the cheapest program with any accuracy there is. I know there are massively expensive programs out there, but man, they are really expensive. PipeMax isn’t that bad IIRC.
