same problem different day. I continue to have what I feel is a low-power problem with this 2001 Cummins with a5 speed. I've cleaned the map sensor, changed fuel filters, new vp44 , installed , installed new airdog. I've check fuel pressure and its good .with quad box on setting 10 the ttruck feels like it has low power it doesn't produce much smoke on level 10, only a slight haze the truck has no top end at all. I'm unsure at what to do next.there's no codes or check engine lights.what would yall tree recomend me do?
