If I understand my younger friends who do calibration, a big cam's lopey idle is usually interpreted as a misfire which does not compute.

To summarize everything they have told me... you want as near to a stock cam as possible in everything....at least, stock idle characteristics...to make your calibration easy.
If you want more power, put a turbo on it.

That is the mindset.....

Big cams, carburetors, and superchargers are for old people
