Can anyone confirm or have you heard that the Cadillac CT5-V Blackwing has something programmed into the computer, to not allow full RPM’s until the car has reached either 500 or 1500 miles on the odometer for the break in period. I vaguely remember seeing this function, so as to allow the engine to slowly break in over mileage driven.
I found the video on You Tube. Look up Konns Vlogs. He shows that the car is limited to 4500 rpms redline until you hit 500 miles on the odometer and then it jumps to 6500 redline.
