    Hey guys bought the truck pretty recently and I’m having issues with the boost. It cuts in and out randomly but a lot more often under a load. It’s showing code 2-5 on the engine faults. I’m not blowing any smoke at all and idles fine. I don’t smell any extra fuel burning and the oil seems fine.
    Anyone on here go through this? What was the fix? I’m thinking a bad injector but it doesn’t have all the signs and it’s directly affecting only my boost. Oil pressure is normal and turbo is 2 months old along with the CAC and new boots.
