Running totally lean after 5500rpm

Running totally lean after 5500rpm
D16Z6
15g turbo
450's
walbro 255lph
ebay fmic
Running 9psi@ectune
The car runes fine in every gear, till 5500rpm that is. After that it feels like fuel is cut and the car sputters and holds in. The A/F gauge also reads lean from that moment on (duh).
New FPR; no result
New pump: no result
Is it possible that the injectors are clogged? If so, why isn't the car holding in/sputtering @ lower rpms?

So, again, what else could it be? And then again: Is it possible that the injectors are clogged? If so, why isn't the car holding in/sputtering @ lower rpms?

How exactly does a fuel filter "seem fine"? Did you flow test that bitch?
Not saying thats your problem, but your problem is that you are overlooking something increadibly obvious, as you would rule out a fuel filter, such you have already ruled out something else.
Post pics of the engine bay pls.
