My car is a 2017 2SS M6. 100% stock, no performance mods.

I've noticed at high RPMs and WOT it surges 1-2 times. Usually at around 5200 and 6000 or so RPMs. This happens in 2nd and 3rd every single time at those RPMs and WOT. It almost feels like pulled timing, but it's very short duration (fractions of a second) and the power comes right back. When it does it in first gear I assume its due to traction control since that light pops up every once in a while. I highly doubt traction is the issue in 2nd gear, and no way the tires are getting loose in 3rd on a straight and 80* temps. It does it in tour, sport, and track modes regardless of whether ARM is enabled.

Anyone else notice this? I really dread having to bring it to the dealer and have some random tech beat on it to replicate the conditions.
