Can you set air fuel ratio without load on it or do you have to set it with load? I am trying to get within ballpark. Thanks

never done this on a mm but when i had my atv tuned...they said it needed to have a load on it. they also told me to put a brand new spark plug in it right before tuning (whatever difference that makes) all this was on an efi tho. they welded a bung into the exhaust and screwed an o2 sensor in it for tuning.
