Should I replace these parts before getting a tune? I bought my car with somekind of aftermarket bellow,MAF is descreened (MAF might not be stock)
Should I get a stock bellow,MAF,and MAF screen before tuning? Or can it be tuned around without issues? I think the screen is an issue?

the bellow doesn't make much of a difference anyways to that doesn't hurt much. Alot of people just like the stock MAF so there arn't any issues. It seems that some people have troubles tuning them in while others seem to do ok. I think professional ones though want a stock MAF just so there isn't any chance of complications on tune day.

A lot of people see no tune change from descreening.
Some do, it depends on whether the air stream coming
out of the lid is biased by any curves.
If you have a screened MAF and tune it all up nice-nice,
then you can swap back to the descreened and know
exactly what you need to retweak (MAF table). The
stocker is easy to swap ends on, so you only need a
mechanically intact junk MAF, it doesn't even have to
work. That and a Torx bit. You can pretty much count
on a (clean) stock MAF with screen to match the stock
table.

If your honest about what is there, then that helps the tuner make the proper adjustments. I have seen a few different people tune a few different ways. Being unaware that there might be a modded/aftermarket MAF on the car or if the ends were ported on a true stocker unit can throw numbers off and can ultimately effect driveability.
