WP Stage 2 — 420–435bhp / 420–430ft/lb
Stage 2 unlocks the true potential of the MK3 Focus RS. With an upgraded intercooler, turbo-back exhaust and induction kit fitted, the 2.3 EcoBoost can breathe properly — and the numbers speak for themselves.
We extract 420–435bhp and 420–430ft/lb from the factory turbocharger, pushing it to its safe limit without compromising engine longevity.
The RS is known for heat-soaking the stock intercooler under hard use — the factory unit simply can't keep up with repeated pulls or sustained track driving. An upgraded intercooler solves this completely, keeping intake temps consistent and allowing us to run a more aggressive calibration with confidence.
The turbo-back exhaust removes the restriction on the exhaust side, letting the turbo spool faster and sustain boost right to the redline.
The result is a genuinely fast car. 420bhp+ through the Twinster AWD system, in a chassis this capable, makes the Stage 2 RS a serious weapon on both road and track.
What's included: Custom dyno calibration on our in-house rolling road with before & after printout
Required hardware: Turbo-back exhaust · Upgraded intercooler · Induction kit
Recommended: 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.
