2 MAF Screens Needed With TT Chip?

[HighMileage]

I read that my factory MAF should have 2 screens. There is only 1 in there.

If I am going to replace my stock chip with a tt chip,does the screen issue matter?

I've got a Cardone reman MAF ordered thru Advance auto. But I told them that if it only has one screen,I don't want it. None of them can answer whether it has one or two.

No sense in getting it if the tt chip will look at it as a non issue.

It says on the website, but if I remember right it says 1!

TT chips are calibrated for one screen (with the stock MAF), since for years most guys would remove one. It will work ok with one or two screens though.
Just finding a good stock MAF will be more of a concern.
