Project Winter Beater

[123abc]

The car has developed what feels like fuel cut at about 4k. Drives around perfect until I start going more than 50% throttle and the boost goes above 12 psi.

I've checked:

-Plugs
-Mafs
-fuel system for leaks
-Boost leaks (none)

On my datalogger the only thing that looks fishy to me is the injector duty cycles go from 20-30% all the way to 80 something percent right before it cuts out.

As of right now, I want to say the pump might be taking a crap? It's an evo 9 unit that I replaced in the winter time a couple weeks before swapping motors.
