Injector problem possibly?

Well I replaced the air intkae temp. sensor, and both crank sensors. The car is now running much better, thank god! But the primary still does not pull the way that it should. The boost is fine but no go. The transition is perfect, both turbos come on strong and pull beautifully. I do however have a spike which is fine, I will possibly port the wastegate and install a Profec b II. The car is running rich, first thing in the morning I get very rich smoke at start-up, and upon tip-in I am getting a black "poof" of rich smoke out the exhaust. We have checked the fuel pressure and volume and it is all within specs. My question is, am I possibly having an injector stick open or drip? thanks

Its sounds like your turbo control or your charge control are stuck, I would check those.

if u got full power at high rpms ill say its not ur injectors. the turbo control actuetor wich is below the turbosnext to the oil pan or the charge control ,above the turbos just before the y pipe it is an actuator just like the first one ; it needs both vacuum and pressure to move.

There is no need to check the actuator, or the charge control. There is no problem with the turbo system, the turbo's build boost fine. The problem is either fuel, timing/ignition. A injector can be faulty even though the car runs fine after transition.

Well i thought that your car was staying stock in the transition mode even though the primary should have the show for himself; leaking pressure back the secondary. Never mentioned about your idle quality; an obius way of telling about an injector stiking open.

Idle seems to fine as of right now. I just wonder if there may be a problem with the injector under load...
