You dont want to mess with the spring it will just make you car run worse.  Why do you want to modify it?

I had the same problem you are having. I bought a rebuilt one from pelican. It's like driving a brand new car.

Save yourself the headache and buy a new, well rebuilt, unit.

If your going to get a new AFM at least check into a MAF conversion.

Well I can't because I prepping for SpecE30 and the MAF conversion isn't allowed.

Look into a rebuilt one at Pelican.  $180 for it...a MAF conversion will run you considerably more.  No power gains to be had either, though driveability improves greatly.

That depends on if your running boost.  The Stock AFM is great on a Stock motor but it does restrict if you’re running over 12 psi.

Indeed.  Can the stock AFM even give a useful output above like 7psi of boost?
