Calibration Focus

  • Fuel mapping optimized for improved airflow
  • Ignition timing refined for stronger mid-range
  • Load tables corrected for smoother throttle progression
  • Consistent power delivery up to redline

Even with stock headers still restricting flow, the intake combined with proper ECU calibration delivered measurable gains and a smoother, more linear torque curve.

This setup represents the first step in the NC upgrade path — with further potential unlocked through exhaust upgrades and camshaft improvements.
