If its missing above 3000, something is wrong, you are right to be concerned.
- Check your firing order closely
- Look under the cap for a burned rotor or rotor button in the cap
- Make sure you have the right MSD rev limiter in it if you run one
- If you run vac advance, disconnect it and try it, sometimes a partially broken wire on the module can intermittently break contact when vac advance pulls in
- Make sure all plug wires are separated so they cant cross fire
- Check for gross vacuum leaks
- Check all plug wire resistance
- Check valve train adjustment and/or bent pushrod
