Black Smoke - help
#2
Restricted on the exhaust side, internally collapsed silencer maybe? Quick test run with the downpipe disconnected would show it up.

Apart from that, what did your pump guy have to say as regards the LDA pin, preload, stop and general pump settings? If the LDA stop is wound too far in, or the spring preload too low that'd cause excessive smoke off boost/on light boost. If the pump has anything in the way of non-factory tuning (steeply ground LDA pin etc/gov mod) that'll affect things too.

If the exhaust doesn't yield anything, I'd probably read up on how the LDA works so you're more familiar with what settings affect what part of the fueling & turn the pin to a less aggressive slope if it's not already on the "tame" side, then experiment with winding the stop out a few turns (best shot IMO as you mention smoke with LDA disconnected) or increasing the preload
