So the company I work for just rebuilt a truck it’s got stage 1 injectors,cam,turbo and a fass fuel system. All new fuel lines. On a hard pull loaded it runs good for a couple seconds until it builds boost which wraps the 45lb boost gauge then starts shuttering and sounds like it’s running dry then if I get out of it and back in to it it still does it. The tune in it is the 550 hot tune. Any help would be apreciated.
Cat3406e runs fine empty but when loaded miss fire
