09 Design FLASHlink Stage 1 – Ford Fiesta ST Mk7
Unlock stronger, smoother performance from your Mk7 Fiesta ST with 09 Design’s Stage 1 calibration. It lifts power and torque across the rev range, sharpens response, and keeps daily drivability calm and OE-like.
Developed and validated over thousands of road and track miles, this calibration is built for repeatable, reliable gains. 09 Design applies OE and top-level motorsport know-how to optimise boost, ignition and torque control so the car pulls harder in the mid-range and keeps delivering to the red line.
- Noticeably more torque for easier overtakes and stronger in-gear acceleration
- Smoother power delivery and improved throttle response
- Retains factory manners in traffic and on long drives
The FLASHlink platform makes updating the ECU straightforward, with robust safety limits retained to protect the engine and drivetrain. It is designed to perform on common UK fuels. For best results use 97-99 RON.
