What do I need for a zo6 maf to work?
I just did mine.

The calibrated unit would require no computer tuning, as it's output mimics that of a stock unit.

At the same hz value from the oem 85 mm MAF, the oem f-body ECM calibration would make the ECM think you were getting more air through the 85mm MAF than would actually be flowing. It should make you run rich because the more air the ECM thinks you are getting, the more fuel it gives you. If you can't change your calibration table and/or don't have a wideband 02 sensor, it's probably not a good idea to change to the 85mm MAF.
As an example, after I installed my 85mm delphi MAF, I was running very rich. At WOT my actual AFR was 11:1. I could see the trail of black smoke my car was leaving from being too rich.
