Without any hardware upgrades, we can add 25HP and 60NM of torque with our Stage 1 ecu software.

Stock: 241 hp / 370 nm

Stage 1:  266 hp / 430 nm

Performance is not just about numbers but the amount of usable power and torque throughout the entire RPM range.

What to expect from Eurosports Stage 1 besides numbers?
– Power on demand response from engine.
– Stronger and lasting pull until redline during acceleration.
– Wider power band.
– Extended RPM range.
– Top speed limiter removed.

Please note that you will need to either purchase our “My Personal OBD Flasher” or ship your ECU to us (indicating licence plate and purchase reference number) to program your Stage 1 software.
