MORE BOOST. MORE POWER. PRECISION-ENGINEERED PERFORMANCE.
Take your forced-induction build to the next level with a custom P1 Underground Boosted Performance Tune. Designed for supercharged and turbocharged applications, our calibrations optimize engine performance, power delivery, and drivability while accounting for the increased demands of forced induction.
Whether you're running a street-driven supercharger setup, a high-performance turbocharger system, or a fully built engine, P1 Underground develops calibrations tailored to your vehicle's specific hardware, fuel requirements, and performance goals.
Performance Optimization
Horsepower & Torque Optimization — Refined engine calibration to maximize usable performance within the limits of your setup.
Boost Management — Optimized boost control strategies where supported by the vehicle's ECU and hardware.
Custom Fuel Calibration — Adjusted fueling strategies to accommodate increased airflow and fuel-system requirements.
Ignition Timing Optimization — Precision-adjusted ignition timing based on boost levels, fuel quality, and engine configuration.
Forced-Induction Compatibility — Support for compatible supercharger and turbocharger configurations.
Throttle Response & Drivability — Improved throttle mapping, power delivery, and everyday driving characteristics.
Transmission Calibration — Available for supported automatic transmission applications.
Fuel-Specific Tuning — Calibration options for 91/93 octane, E85, and other supported fuels and fuel-system configurations.
Built Around Your Setup
No two boosted builds are identical. Pulley sizes, turbocharger specifications, injector flow rates, fuel systems, engine modifications, and boost targets all influence how your vehicle should be calibrated.
At P1 Underground, we take these variables into consideration when developing your tune, with an emphasis on delivering responsive, consistent performance while retaining appropriate engine safety strategies.
From mild street builds to dedicated high-horsepower applications, our goal is simple: deliver a calibration that works with your hardware, not against it.
Requirements & Compatibility
Compatible supercharged or turbocharged vehicle.
Supported SCT, HP Tuners, or PCMtec tuning platform, as applicable.
Complete vehicle and modification information.
Properly functioning engine, ignition system, and fuel system.
Additional datalogging or revisions may be required depending on the application.
Important Information
Performance results vary based on engine condition, boost pressure, fuel quality, modifications, and supporting hardware. Some applications may require additional tuning services, hardware upgrades, or dyno evaluation.
Tuning cannot eliminate the mechanical risks associated with increased engine output. Compatibility and supported features must be confirmed before purchasing.
