Doubt it. His pump time right before the C16 time was not that impressive to say the HEADERS OMG OMG. This was supposed to be a revised flash to take account for headers so we would see a difference in all the different flashes (93/104).
But 11.41s 60-130 pump time today right before the C16 switch?? Compare that to his 11.91s summer time with no headers and heavier wheels.
The 0.5s difference could be from the -1800 DA change and the difference in wheel weight. I would say the increased timing and C16 made the real difference.
Not enough evidence for me.
