WP Stage 1 — 270–280bhp / 320–340ft/lb
The 2.0 EcoBoost in the ST250 is a well-proven tuning platform, and the factory 247bhp calibration leaves a significant amount of performance on the table. With a full recalibration of boost pressure, ignition timing and fuelling maps, we extract 270–280bhp and 320–340ft/lb — a noticeable step up in power and torque across the entire rev range with no hardware modifications required.
The difference in the way the car drives is immediately apparent. Throttle response sharpens up, the turbo builds boost earlier and harder, and the flat spots in the factory power delivery are cleaned up entirely.
The mid-range torque improvement is the biggest change — the ST250 goes from a car that needs to be revved to a car that pulls hard from low down.
What's included: Custom dyno calibration on our in-house rolling road with before & after printout
Hardware required: None
Advised: Induction kit · 99 RON fuel — Shell V-Power or Tesco Momentum

WPFlasher — Remote Tuning Option Can't make it to the workshop? Our WPFlasher device lets you receive your custom calibration remotely.
You read your stock ECU via the OBD port and send us the file, we build your custom tune and send it back, and you flash it yourself at home.
If you're able to take data logs, send them over and we'll refine the calibration further. Select your preferred installation method at checkout.
