Thanks for the request! I would start with fuel pressure . If this unit has EGR system , the fuel pressure should be measured on the fuel rail on the left side just above the high pressure injection pump . Fuel pressure should be around 60 psi throughout all ranges. idle , high idle and full load down the road . I would connect a mechanical gauge and raod test with it connected to drivers mirror and see if it stays around 60 all the time .
