I can rev it and no boost still no codes
If the turbo shit the bed I should have a code right
Step 1: Make/buy a boost leak tester and see if it has a boost leak, that will 100% cause the symptom you're having (not the codes tho).
Step 2: If fixing the boost leak(s)/none found doesn't fix the issue, watch desired and actual rail pressure to see if it's not building proper pressure. There are many causes for this and we can look at if step 1 doesn't fix the problem.

Isn't the LML the one that's prone to ghost code on delete tunes? I remember reading about it when tuning was new for the LML. Something to do with an unrelated code needing to be disabled that fixed the issue. And not all trucks suffered from the issue. Always results in a limp mode with no codes or DIC warnings.
I think there was two ways to get it out of limp, reflash the ECM, even flashing the same tune will work, or adjusting the offending code and flashing that tune in
It seems like this may be a possibility

On the cold side should I be able to squeeze the hose almost like a radiator hose or should it be stiffer so it holds boost?
I’m in brownwood but thanks for the info everyone out here works on powerstrokes or Cummins and don’t want to touch a duramax
Yes that one
You MAY have a bad map or circuit for the MAP. See the attachment. If you have a scan tool, check BARO vs MAP. BARO should remain relatively flat while MAP should change quite a bit if boost actually increases.
I'm thinking that P026D below may be the answer to your problem just because it mentions a few of your codes.

I changed the fuel filter and it was clean diesel but I’m gonna check the fuel rail pressure last time I looked it was around 21000psi if I remember correctly

Ron I can get a snapon scan tool from a buddy and that’s what the codes were from everything else is from my edge that I use as gauges or the v2 for my efi live

Bd I may have a friend that is a customer of mine that mainly works on powerstrokes that might have the leak down tester but it should work on a lml so I’m gonna see it’s kinda hard when I’m looking and can’t hear anything over the engine

Here is what I found tonight
I also have a video from the snapon scan tool that shows baro and map pressures

Ok that one won’t upload but baro goes up to 51.0 and map stays at 28 even up to 3500
Also fur rail pressure never went above 5800 psi
I just need to get this fixed any help is truly appreciated
