Traction control light flashes full throttle at highway speeds (sometimes doesn’t shift)

I see you noted the tires are staggered properly. FYI I just solved a similar issue with my manual trans., but I rotated the tires by mistake and the guys here helped me solve it. So I know for a fact that if the tires are not exactly what the diameters were like 225/xx/18 front and 245/xx/18 rear this will happen. I could rev to redline in 1st thru 4th but when I would get into 5th and over 80MPH the car would flash the traction control light and cut boost etc. and that was the fastest it would go.

Just make sure they are correct sizes and not off by very much if they are larger. The staggered diameters are what matter. Turn off traction control to prove it.
