I see that most of you guys have the air flow meter before the compressor. Why is that? The factory did the same thing on the E23 745i.

What if I put the AFM after the compressor, after my intercooler, much closer to the throttle body. Would that make a difference in anyway?

Which way is better.


below is a link to a guy that put the AFM after the compressor on a ford prob and had much better driveability.

By the way, this is for my 87 325i, but the general idea is the same as all cars with AFM and motronic.
