Default Pressure drop across the Duh FMIC? 1psi? more?

I recall seeing data on AWE's website comparing the stock unit vs. RS4 vs. AWE ICs where RS4 and AWE have nearly identical pressure drop across the rpm range. (roughly 1psi pressure drop avg)

What about the Duh FMIC?

For the price, it needs to be 2x better.

Default not sure what the pressure drop is, but if youre planning on going bigger than K03s i'd steer clear.

From everything ive read it seems like the DUH designed to flow the amount of air that K03s push and gets a little restrictive when you get into the higher aiflow numbers.

Default I do not think that is true at all. Eric claims a very low drop at k03/k04 level

It has a average drop at higher levels, well within an acceptable range. IIRC - RS4 peeps in Europe run ~28psi w/ K24s and they love the DUH.

I have not tested pressure drop yet, but I hit 25-26psi at about 3100-3200rpms right now. No complaints here...

Default How is that tested?

If you know, let me know. Then, maybe I could give you some #'s.

It seems to be workin out for me. My only complaint is seeing coolant temps above the norm on hot days... I blame that on myself for not installing an EFK as recommended by DUH.
