Tuning Boost in RomRaider

  1. Log Boost
  2. Reaching Target Boost?
    • No? Increase Max Wastegate Duty Cycle & Log Again (Over 90% not safe for prolonged periods)
      • If WGDC is above 90% & still not reaching target, May Need pill or prodrive/GM solenoid
    • Yes? Boost is Tuned, maybe focus on improving spoolup early on
      • High WGDC Early in RPM range to keep WG closed and improve spoolup
  3. Tuning Turbo Dynamics?
