i´ve been driving some years with my AFR gauge and i can tell. in CL everything is as usual, in OL it is a lot better, because to much fuel is even worse. but i was aiming at the optimal spot and 4 klicks are still a little on the rich side.

That sounds good. Using a UEGO (your AFR) is a great way to confirm wear you are. If you tune open-loop fuel using air-box modification, you may want to tap a k-type thermocouple into one of the exhaust runners near the exhaust port just to keep an eye on things and make sure that the lessened enrichment doesn't get you into exhaust valve or other thermal issues.
