Looking at your smoke opacity test which was 0.67 with a pass limit in your country of 4.00
I would say that maybe your engine isnt getting full fuel.

We in the UK have a similar test where the pass limit is K-3.00 for Turbo engines, and K-2.5 for non turbo..

Before adjusting anything, I would check that all the 'alda' lines and the solenoid (if fitted) are correct and not leaking. Maybe one pipe etc was mis-placed during assembly....

Another check would be to confirm the Turbo is in fact developing the correct pressure...

Maybe worth confirming the Injection-Timing, as its all been apart recently...

If all is well, and if you have access to a 'smoke-tester' I would then start to adjust the Alda to give a reading of around 2.5-2.8 on a F.A.S. test (Basically floor throttle for half to 1 second and take readings).....Not much point in going higher on the smoke....

By that time you should be running pretty well, and still have a good clean exhaust....

Back off/loosen the injector line nut and see if the threads have been cross threaded. Look at the cone shaped tip of the injector line and the reverse cone where it fits into the injector and see if they were damaged or something got pinned under them when they were tightened down.
You can loose alot of fuel from a tiny fuel leak.
