Tuning without a dyno

I'm not sure if I have this in the right section. I'm interested in tuning but for the moment no access to a dyno. Can you road tune with out a dyno and how good would the tune be without a access to a dyno?

Hi Randy follow this link to a Webinar on tuning without a dyno

You can road tune to adjust the fuel mixture using a wide band lambda data. To tune ignition, and thus maximize power, you will need to have access to a dyno (which most people think isn't available, but we can usually find a place with an hours drive of anywhere in the USA).
