  1. I have a 2003 cxu613 with a 460 and am having a boost problem. New air to air with new clamps and tubes. New waste gate accurater. Boost comes up to 18 psi then all at once without no warning it comes alive and jumps up to 32 psi and pulls it's guts out. Next time it may not go up seems like no boost until it hits 1400 rpm. Warning light comes on and readout on dash screen says number five injector problem. New injectors with what I call injector drivers. New ecm and manifold gaskets new wiring harnesses. Anybody got any ideas
  2. I have been having troubles with my wastegate. my turbo boost normally runs 27 to 32 but my lighting bolt comes on and my boost will not go over 20 psi.I can shut the truck off and restart it and its works fine. it will reset itself after a while. my local mack dealer installed a new piece on the turbo with a new hose to my intake . they pressure tested my air to air and said it was ok. the air to air was replaced last year with a new one. I have been dealing with this for over a year and get charged every time they try something. today they said the new part was sticking and cleaned it and I got 5 miles away and the same thing happened. I hop someone can help me. I love my truck but its at my mack dealer too much and it is driving me to the poor house. Thank you in advance for any help I may get
