I'm betting the tune just needs a tweak - they'll spot what happened in the logs, make a small adjustment and you'll probably never see it happen again.

These things happen - once I had a misfire/cut on upshift on my Nissan GT-R. The car had had an ECU and a TCU tune. The problem was it was hitting the RPM limiter at the exact same time the TCU wanted to upshift - sometimes the ECU triggered the cut, mostly it did not.

The solution was to raise the rev limiter of the ECU by 50rpm. I never had that issue again.
