Hie techniciansI recently did an engine rebuilt on that D6A emgine I sent the injectors and pump for service and they changed pumping elements and nozzles but the truck is emitting excessive black smoke,it starts well but smoking and has no power,the turbo boost is fine,the supercharger is okay,the air filter is new,the retarder is not stuck I just want to know if anyone can furnish me with calibration specifications of that pump just in case it's over fuelling
