With the GPF and catalytic converter removed via a performance downpipe, and supported by an upgraded intercooler and intake, we extract 370–385bhp and 385–400ft\/lb — the maximum the stock turbo can reliably deliver.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eRemoving the GPF and cat frees the turbo to spool faster, sustain higher boost levels, and breathe freely at the top of the rev range. Combined with the intercooler and intake upgrades from Stage 1+, the car gains noticeably sharper response, a broader powerband, and a much more engaging exhaust note — the MK4 ST is quiet from the factory, and a decat downpipe transforms the soundtrack.\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\u003eRequired hardware:\u003c\/strong\u003e Performance downpipe (decat or sports cat) · Upgraded intercooler · Performance intake\u003cbr\u003e\u003cstrong\u003eStrongly recommended:\u003c\/strong\u003e Clutch upgrade · Uprated spark plugs\u003cbr\u003e\u003cstrong\u003eAdvised for track\/hard use:\u003c\/strong\u003e Boost pipe kit · Breather kit · Oil cooler\u003cbr\u003e\u003cstrong\u003eRecommended:\u003c\/strong\u003e 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\u003cstrong\u003eWPFlasher — Remote Tuning Option\u003c\/strong\u003e\u003cbr\u003eCan't make it to the workshop?
