Q45 or Z32 afm

[tardo00]

the q45 are very cheaper and easier to find. Are they as good as Z32 to
tune a gtr up to 600hp. what is the difference between the two. I know z32 are 80mm and q45 are 90mm. but anything else ?

The nismo MAFs are 70mm. The nismo are rated higher than the Z32s. Q45 is not on a car, I would think they're not as good. I'm guessing they're cheaper...
