OK- Now that I got that out of my system...


What "full shibby deletes" have been done?
Can you restore the ECM to stock and see if these codes clear and the usual delete codes do appear? That would indicate an issue with the load.
Go back over your installation of the deletes for any possible mishaps like broken connections or wires from gorillas under the hood.

Things to think about.

These codes are all stored non are active right now everything is tight everything plugged in and the turbo will spool then tone changes like the veins open up this happened around28psi then u drop down to 22psi and sometimes the service exhaust system will flash in the data center In the dash it's weird
