Just to confirm: When you calibrate, you "undershoot" the correction by half? For example, if it was 10% under, then you add only 5%, etc.

Black smoke while accelerating could also be if you are leaking compressed air somewhere between the turbo and the intake manifold. If replacing the injectors doesn't clear that up, then you should check for loose air hoses.
