the system is originally off a normally aspirated 4 cylinder engine and uses an air flow meter. It is multi point injection not single. Fuel pressure is 200kpa at idle and 250 at zero vacuum. This is fine according to the service manual.

is the air flow meter a vane type or a hot wire, or thick film type?
also where is it mounted? as in before the turbo intake or between the turbo and the manifold? it needs to be before the turbo intake for most consistant operation.
is it possable to get trouble codes out of the ecm? the ones here (colonies) have the ability to at least give a flash/check engine light code.

its a vane type mounted before the turbo intake. It has a fault code operation but evrything is working. I tried even changing the computer but it made no difference.
