thats normal.

Redline from the computer is 10505rpm before it cuts fuel/spark.

Redline for the motor is around 5500 in it's stock form. It's not designed to rev high. All the power is made from around 3000rpm-4500rpm. That's max torque and hp.

I can't see the photo but sounds like a V6 tach in that! I will see what my 92 5.0's is tonight.
