Lexus afm

[realdeal]

Has anyone installed the Lexus afm and custom air screw on the 7mgte? I am wondering how much the air screw needs to be screwed in? How much of the gap should there be? I have been running this mod for a few years now with no problems. This year I did a tune up and now I have boost cut. I lowered the boost and it is still happening, but only on wide open throttle. I am running stock injector and stock turbo, and thought maybe it's running too lean, so I screwed in air screw in all the way but isn't fix the problem. Now my check engine light comes on, but only at an idle. It goes away after the rpms pick up. Did I screw it in too much? Is it too rich now??? I read that with the Lexus afm you need to get the longer air screw and larger injectors. Can anyone offer me some insight?
