Th400 swapped. Cant rev past 4500rpms

I sold my camaro. New owner slapped a th400 in it (good man). He disconnected my n2mb wot box, by removing the coil harness extension that i used to splice it in. So the wot box has zero control over ignition. Its out of the picture completely. (No sure why i mentioned it)

He removed the clutch pedal, but he said he left the wiring harness portion of the pedal connected. The car acts as if it is in competition mode, launch control. I had him mess with the traction control button, and even press and hold it to disable all traction control. He also tried removing the clutch pedal wiring harness.

Still cant get past 4500rpms.

Has anyone had this issue with their th400 swap from M6?

I checked the tune and even R and N are set to 7300…

Wheel speed RPM limiter - might be the ECM isn't seeing vehicle speed, and that table is still set like stock...
