Mini Max return to stock problems
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.
