Crazy question. my car currently has a c&l 80mm maf that is dialed in. i have a 90mm lightning on the shelf that i thought about using. question is would there be any benefit swapping mafs?

do u have 90mm piping ir 80mm piping?

I have a 4" elbow and 4" pipe with a reducer going to the c&l.

then 90 is best

Thanks.
