Mini Max return to stock problems

[work truck]

After 40K+ miles, I have to return to stock for smog check. I replaced the DPF, left the S&B intake on, then downloaded the stock tune on the mini max. My first test drive resulted in almost no power, about 8psi boost max. I returned home and shut it off. Starting it again resulted in a CEL. Diagnostic called it a P040D. I cleared it and drove it again, this time resulting in P040D and P00088.
I will add that 40K+ miles with dpf delete had been FLAWLESS up till now.

After some research, it would seem that the EGRT sensor A is faulty. I'm just not sure why it just showed up immediately after returning to stock.

When was the last time you updated? There was a " return to stock bug " fixed recently I believe.

Mine is version 35. I didn't know about 36 and 37. I'll give it a try.

36 had a return to stock bug fix. Not to sure if it will help your situation but might be worth a try.

because the delete tuning ignores that sensor

Is that the same sensor that feeds Pyro 1 on the screen? Because it quit working some time ago.... just reads 92 degrees all of the time.

ahh, yes, that would be the problem. it ignores the other sensors, but it seems that it shuts off the DTC for that sensor also

Gonna buy a new sensor from Ford when they open, hopefully it cures it.
The P0088 code (fuel rail pressure too high) might go away. Initial research leads to HPFP replacement which scared me. But after reading an Oasis report posted on here, it stated NOT to proceed with pump replacement if other DTC's are present. I'm getting both codes at the same time.

fingers crossed that the temp sensor licks it
