Very nice clean setup. The tap into the manifold is a smart move, keeps intake flow on the "cold" side of the engine.

Any issues with operation of the AFM the way you have it? Those things usually are placed so the axis of rotation of the gate is somewhat vertical, and yours is almost horizontal.

Also, I don't see an idle control valve - are you using a MAP (Manifold Air Pressure) sensor?

No, I just removed the ICV alltogether. Idles fine without one, just raised idle around 100rpm..
No issues with the AFM, this engine management is an old-ass crap, so honestly a 1-2% difference in measured flow just can't be noticed.. I'll be ditching it later for a standalone.
