09 Design FLASHlink Stage 01 to Stage 02 Upgrade – Ford Fiesta ST Mk8/8.5
Already running 09 Design FLASHlink Stage 01 on your Fiesta ST Mk8 or Mk8.5? This upgrade moves you to Stage 02 with a revised ECU calibration for a clear step up in real-world performance.
Stage 02 releases up to 258 hp and 290 ft-lb from the 1.5 EcoBoost, with stronger torque across the rev range for faster response and confident overtakes. It remains road legal and keeps the factory GPF and catalyst in place, so everyday use stays clean and fuss-free.
Installation is simple. We send you the updated calibration and you apply it via the FLASHlink app in the same way you did Stage 01. Drivability stays smooth and predictable, with reliability at the core of the tune.
For best results, pair Stage 02 with the 09 Design carbon induction kit and the 09 Design high-performance alloy intercooler. These help the engine breathe and control intake temperatures, supporting consistent power and efficiency.
Requirements: You must already have the FLASHlink app and a Stage 01 calibration on the vehicle to install this upgrade.
Fitment covers Ford Fiesta ST Mk8 and Mk8.5 models worldwide, pre and post facelift. The correct calibration is supplied to match your VIN build data. Please use our vehicle lookup to confirm compatibility or check the Vehicle Fitment tab for full details.
