Im having a little issue with this 2011 Cadillac ctsv. When cruising an hitting throttle the car will pull a lot of timing out and stumble. I have retarded the timing and it still does this. Im not sure if im hitting a threshold that would cause this. it will pull back to -15 degrees of timing. I do notice kpa is over 225 sometimes higher. maybe im missing something. Most of this happens around 2500 rpms. the car runs great above 3000 rpm
Car has smaller pully making 14 psi and we have ID850 inj.
you can see this at 4.19 min in the log(kretard3)
3.10 in the second file.
