What to Do If Your Vehicle Loses Power After Installation

  • Verify the tuner tune file for LML Duramax was fully flashed and no programming errors occurred.
  • Inspect exhaust pipe connections and gaskets to confirm there are no exhaust leaks causing pressure leaks.
  • Confirm all OBD cables are securely connected and there is no loose wiring for the tuner module.

Long-Term Maintenance Tips

  • Regular Inspection: Every 5,000-10,000 miles. Inspect exhaust pipe joints, gaskets and fasteners for exhaust leaks.
