Stage 1 Engine Chip Tuning | Subaru

This service involves reprogramming the engine control unit (ECU) to optimize fuel maps, ignition timing, air-fuel ratios, and boost pressure (for turbocharged vehicles) without requiring hardware modifications.
It’s a safe, reversible tuning option that enhances throttle response, power, and efficiency.
For Subaru models like the WRX (2.0L/2.5L turbo) or STI, the tune is tailored to the boxer engine’s unique characteristics.
For other vehicles (e.g., BMW 3-Series, Audi A4), tuning adjusts parameters to match manufacturer specs.
The process uses professional tools like Cobb Accessport or EcuTek, ensuring compatibility and reliability.

• Power Gains:

  • Subaru WRX/STI (2.0L/2.5L turbo): +20–40 hp, +30–50 lb-ft torque (e.g., WRX from 268 hp to ~300 hp).

  • Other Vehicles (e.g., BMW 320i, VW GTI): +15–30 hp, +20–40 lb-ft torque (e.g., GTI from 220 hp to ~245 hp).
