  • Overheating: Increased power can lead to higher engine temperatures.
  • Loss of power: Sometimes, modifications can lead to a decrease in performance.
  • Check engine light: New mods may trigger sensors, resulting in warning lights.

Addressing Engine Knocking

Engine knocking is a serious issue that can lead to significant damage if not addressed promptly. Here are steps to mitigate this problem:

  • Use high-octane fuel to reduce knocking.
  • Re-tune the ECU to optimize fuel and timing settings.
  • Inspect the ignition timing and adjust if necessary.
