Cooper S Countryman
B48 / B46 (US)

The engine gains are identical to any other Cooper S — the B48 neither knows nor cares what body it sits in. What changes is the experience: because the F60 starts with more mass to move, the extra 80–120 Nm of mid-range torque is arguably more transformative here than in the hatch. It is the difference between working the engine and riding the torque.

Both. The F60 Cooper S came in FWD and ALL4 forms and Samuel calibrates for each — the ALL4's extra drivetrain loss shows at the wheels, but its traction lets you use full throttle earlier and more often. Just note which drivetrain you have when you send your build details.

Take it from 189–192 bhp and 280 Nm to 245–260 bhp with 360–400 Nm, purely through software flashed over the OBD port. In-gear acceleration is where the change lands hardest — motorway slip roads and loaded overtakes stop requiring a downshift and a plan.

For the full figures, yes — 99 RON lets the calibration run the ignition advance the numbers depend on, and it is strongly recommended on any aggressive map. If you can only get 95 RON locally, say so up front: Samuel writes the file to the fuel you will genuinely use rather than leaving the knock control to bridge the gap.

It never is. Remote delivery means the Countryman sits on your drive throughout — the calibrated file arrives in your flashing account within 24 hours of ordering, and writing it to the car takes roughly 15 minutes. For a vehicle doing school runs and holiday duty, zero downtime is the point.
