HPF STAGE 1 | 440KW

FGX / FPV S/C 5.0L | HPF STAGE 1 | 440KW

The FGX/FPV GS, GT, and GT-P Supercharged Boss 5.0L Stage 1 upgrade enhances engine performance and efficiency with premium components and expert tuning. The process begins with installing a high-flow K&N air filter to improve engine breathing and airflow. A Walbro 460 fuel pump is then fitted to ensure a robust fuel supply matches the increased air intake. Mandatory for the Ute and optional for the Sedan models, a Manta dual 3” cat-back exhaust system is added to optimize exhaust flow and reduce back pressure, boosting engine efficiency.

After component installation, our technicians perform a custom ECU flash tune using advanced HP Tuners software on a dynamometer, optimizing the engine for maximum power, torque, and fuel efficiency. The upgrade concludes with thorough road testing to ensure peak response and drivability. A dyno graph is provided, detailing the power and torque gains achieved.

This Stage 1 upgrade is modular, allowing future enhancements without redundant costs. HPF guarantees maximum safe performance, reliability, and drivability.
