Two different tachs?

Yep...many people don't know the tach is variable and wherever the redline is, is where the rev-limiter cuts in. If it's reading 5k when cold, the engine will cut out at 5k. That was not the case for the E46 M3 with variable tach.

Good to know, I never had the desire to actually find out.
