For me, it was bucking/heavy hesitation under load. Switching to a freshly cleaned, low mileage set of injectors fixed it.

Another of course, is to visibly see fuel leakage when the rail held above the engine block and the fuel is pressurized.

Related, but not injector-specific, is leakage in the injector o-rings.

Decreasing boost at WOT is often a sign of a clogged cat.

i was actually referring to the main cat between the pre-cat/downpipe and the cat back exhaust.
