  • Ignition timing advance and knock detection
  • Boost pressure and wastegate control
  • Fuel pressure regulation
  • Coolant and intake air temperatures
  • TPS and MAP sensor response
  • Injector duty cycle and pulse width

What We Look For

Performance Issues

  • Lean or rich conditions that rob power
  • Timing that’s too conservative or aggressive
  • Boost control problems and surge
  • Throttle response issues
  • Part-throttle tuning opportunities

Safety Concerns
