Then I dare to say that the cam isn’t very large to begin with.
Dyno testing is about maximum and maximizing power where it’s making the power. If you or anyone wants to dyno there grocery getter, well OK then, have at it.
But to say, “it can be nice to know how close the tuneup is” is one very crazy thing I never heard of before. To me that’s literally insane. If you can smell it a rich runner, then pull a plug, read it, adjust the carb etc… for around town driving.
The dyno tune is only good for the dyno and taking it directly to the track expecting it’s a good tune is again, crazy.
