Default Tach stops moving at 6600 rpm on dyno

Redline is 7k on the car and you can hear it hit the limiter in the video. Do other people have this problem?

Also, the PT4400 now flashes to 6k on the dyno. Anybody else get that much stall speed from big heads/cam upgrade?

Scanner says 7k. The tach moves pretty well and then stops at 6600. You can hear the engine rev to 7k.

7k damn. I know my tach is slow. If I spin through water or something in 1st, its already hitting the 6300 limiter but tach shows about 5800. If I have traction its usually behind 100rpm or so at wot.
