2017 Jaguar F-Type SVR (No Modifications have been made)

I was driving aggressively on Saturday doing in excess of 100 mph and noticed something of a misfire when I pushed the car past 120mph quickly. As this was the first time I had felt it, I accelerated a few times rapidly past 120 and every time it seemed to misfire or pause at 120MPH. I switched it into Dynamic mode and accelerated past 120 again to see if the results were the same. You guessed it... they were. As a final act, I slowly accelerated through 120 and there was no misfire!!! Aside from that, there are no other problems with the car.

SO, MY QUESTION IS..... What could be going on? Could my timing be off but only showing at 120 mph? Could I have a bad spark plug/ignition coil? Any ideas would be great before I take it to someone.

Thank you all in advance for your assistance over the last year of ownership.

 

Not timing. Possibly injector issues? (Sticking, not opening all the way)

QUESTION TO OTHERS: Are there secondary injectors that come into play at high RPMs or loads?

If it were a bad plug/ignition you would probably have a passive background OBD code. I'm sure a shop would look at the OBD codes as a first diagnosis.
