As the title indicates, my 2017 C2S is having a very infrequent issue where I smash the gas and the transmission kicks-down as you'd expect, but it then bogs down and the traction control light flashes a bunch. I always drive in Sport mode and have only observed this when I'm cruising <50 mph, so probably in 4th gear, and then it kicks down to 2nd and bogs, but I could be wrong. It appears to bog all the way through second gear and then third gear hits like a rush. It's almost like it's limiting torque...

Since this doesn't happen often at all, it's not easy to reproduce - nor fun - which challenges my ability to isolate the initial conditions and potential causes.

Other info:
2017 with 19k miles
Sport Cats installed from reputable company on this site.
The car was tuned one month ago by a highly recommended company on Rennlist. I drove it many times without experiencing an issue - at least 500 miles - and just noted this last week. I did also contact the tuner and prefer to not share their info until this is worked out.

Any thoughts? How to investigate?

Thanks!

Turn off the traction control and repeat.

Report back.

Sounds like your traction control is kicking in.

As above, turn it off and try again. Expect a loss of traction.
