This Mitsubishi Lancer was turbocharged by Road Race Motorsports. They used the PSC1-018 which is designed specifically for cars with Karman Vortex air flow meters. The PSC1 allows the use of larger injectors which provide the additional fuel required in boost. When properly tuned, the PSC1 provides stock drivability and fuel economy at light load and the desired fuel mixture in boost.
Access to the ECU is right behind the glove box. The PSC1-018 comes with detailed instructions that simplify installation.
