    2020 Denali with derringer threw fuel pressure code and limp

    So temps are in the 20s currently. In terms of the fuel filter I only have 10k on the truck so in My mind the filter traditionally should be fine however you can never be certain with fuel sources.

    p0400 and p0100

    We never figured it out and they never ended up causing a problem. I have seen this many times since in other vehicles also. I have never experienced any negative side affects from it.

    lmm boost issues "vanes"

    All the vanes are moving freely and assembled correctly. Gonna try ECM swap tomorrow. And after that it's going to the dealer. Unless for some unforeseen bad luck both vane solonoids are bad

    lmm boost issues "vanes"

    pretty positive its not a mechanical issue. Even when commanded to open or close the vanes will not move. Something is not telling the solonoid to open or close!! is there a vane module? or is it in the ecm, and if so could the ecm be bad??

    Ok so Iv got an lmm with one of Trents twin kits on it. It started lagging real bad. So scanned it and found that the vanes were open. I had another good stock turbo laying around, since I figured the vanes were prob. stuck. I switched them out and to save time I just left the turbine housing on...
