If you haven't already done so, search 'tightening torque for metric fasteners' and you will find nothing greater than 100 Nm recommended for a grade 8.8 M12 bolt. Based on this and the gut feel that the extra 90 deg is a lot, I went down my cautious path.
Good news it isn't that much work to replace the nuts & bolts. Please post whatever you decide.

The 90 degrees is about an additional 25-27Nm...my torque wrench is electronic and recorded the peak and I looked because I was curious.
The cost is really in time and frustration. Now I have to wait until next weekend to complete the job while waiting for parts. Glad this isn't my DD. All of this is 1st world problems, I know!
To be clear, I decided to replace and retorque to the 8.8 spec.
