With a full recalibration of boost pressure, ignition timing, fuelling and wastegate control, we extract 335–345bhp and 340–355ft\/lb from the standard turbocharger. No hardware modifications are required.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe factory 280PS calibration is very conservative, and the 2.3 EcoBoost has significant headroom beyond what Ford deliver. A Stage 1 remap transforms the way the car drives — sharper throttle response, stronger boost through the mid-range, and a top-end pull the stock car simply doesn't have. Combined with Ford's electronic limited-slip differential, the extra power is deployed with genuine precision.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWhat's included:\u003c\/strong\u003e Custom dyno calibration with before \u0026amp; after printout\u003cbr\u003e\u003cstrong\u003eHardware required:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003eStrongly recommended:\u003c\/strong\u003e Clutch upgrade — the stock clutch is a known weak point on tuned MK4 STs and may slip under the increased torque\u003cbr\u003e\u003cstrong\u003eAdvised:\u003c\/strong\u003e Induction kit · 99 RON fuel — Shell V-Power or Tesco Momentum\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e📖 \u003ca href=\"https:\/\/wayside-performance.co.uk\/pages\/mk4-focus-st-tuning-guide-stage-1-stage-1-stage-2\" target=\"_blank\" rel=\"noopener\"\u003eRead our full MK4 Focus ST Tuning Guide →\u003c\/a\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eWPFlasher — Remote Tuning Option\u003c\/strong\u003e\u003cbr\u003eCan'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.
