2001-2003 WRX STI Kits:
Stage 1 - 225kw
Stage 1 for the Subaru STI involves reprogramming the factory ECU with
ECUTEK software. ECUTEK allows Autotech to remap the fuel and ignition
tables to provide more power and better fuel economy right across the
rev range. More boost can be added to increase engine torque, providing
stronger acceleration and unlocking the power of the Subaru boxer
engine. Autotech custom tune each vehicle to ensure engine safety and
maximum performance.
