Same thing as yours though, right now my car is sitting in the garage, I'm putting a new engine in due to this one having oil pressure issues. I have a completly differant tune to try as I'm sure it has some thing to do with the tune, I swapped. In q tune from another car with same setup and this issue went away but a few others showed up.
I think there is either an issue with the hardware in my ecu or something went wrong durring flashing we will see and I. Will update
