You serious mate?

You shouldn´t hear your AFM at all. If you do, you need to go to the doctors. :rofl:

Seriously, you sure you not hearing your aftermarket fuel pump? This is common.

yeah something i didnt think of fuel pump is now hot wired so now has 14v at idle instead of 9v so i guess is pumping and returning lots of fuel at idle now.

might be the air through the filters, that can make a noise, depends what you are running, if the meshes are bent it may make a noise, but mine dont, and the ken and nigel is in the standard airbox, so cant hear that!
