Performance Package 550HP is built for serious power and high-boost reliability. Featuring a large-frame turbo, high-flow fueling, and advanced cooling, this setup delivers maximum horsepower while maintaining drivability. Designed for track use and high-performance street builds, this package requires a built EJ engine to handle the increased power.

• Holds boost through redline & beyond
• Maximum bolt-on power before built internals are required
• Optimized for high boost & track applications

• Cobb Accessport V3 – Essential for ECU tuning, real-time monitoring, and data logging
• Cobb Intake with Airbox – Improves airflow, throttle response, and induction sound
• Invidia Catted Downpipe – Reduces exhaust backpressure for better turbo efficiency
• Injector Dynamics 1300x Injectors – Provides increased fuel flow for high-boost setups
• Blouch Dominator 3.0G2-R Turbo – Holds boost to redline, delivering the highest power levels
• Cobb Front Mount Intercooler Kit – Keeps charge temps low, preventing heat soak
•  IAT Relocation Kit – Ensures more accurate tuning & improved efficiency
• AEM 340 LPH Fuel Pump – Ensures consistent fuel delivery under load
• Cobb 3-Port Boost Control Solenoid – Provides precise boost control and improved response
• IAG Fuel Rails/Lines Kit or Cobb FPR Kit – Enhances fuel pressure stability and distribution
• Turbo Inlet Pipe (Cobb 2.4" or Killer B 3") – Reduces restrictions, improving airflow to the turbo
• Full Turbo-Back Exhaust (Optional but Recommended) – Helps reduce backpressure, improves turbo efficiency, and enhances sound
• Cobb Front Mount Intercooler – Larger core for improved cooling and sustained power
• Pre-Dyno Inspection – Comprehensive check to ensure vehicle is mechanically sound before tuning
• Baseline Dyno Run – Establishes pre-upgrade power levels for comparison
• Post-Upgrade Dyno Run – Verifies power gains and ensures optimal tuning calibration

• 91 Octane required (E85 recommended for maximum gains)
• Custom tuning required
• Pre-dyno inspection is mandatory
• Oil pan upgrade recommended
• Recommended: Built EJ such as IAG 550 or Greater for increased reliability at high boost levels
