s2 rs turbo
runs really badly and it hurts my eyes as super rich

things we started with
took all injectors out and turned on ignition with link across the relaypump running , no fuel at all comes out . push down flap and the head squeals and fuel comes out . all good there I feel
from a cold engine under cranking the cold start injector fires , also I can force it to fire by sending a negative to the plug under the manifold that goes to the sensor . again I feel thats correct

once warmed up if I disconnect the plug to the black box by the metering head it also makes no difference , popping through the exhaust and revs at 2 k but it stinks of burnt fuel

all new ignition leads , cap and arm with spark plugs
new fuel pump and tank also filter

if I adjust the 3mm Allen key to make it weaker it runs worse and dies

what am I missing here . changed the metering head and flappy thing assembly for another that was running last week so assume its a good one
