About this tune
The later F54 JCW Clubman ALL4 makes ~302–306 bhp factory from the same B48 turbo four. Stage 1 is software-only; Stage 2 adds an intercooler, sports cat/decat and intake. The heavier ALL4 body adds drivetrain loss, but the engine makes strong numbers at the crank. 99 RON strongly recommended.
MINI John Cooper Works Clubman ALL4 tuning
The MINI John Cooper Works Clubman ALL4 (F54, 2015–2024) runs the B48 / B46 (US) 2.0L turbocharged inline-four (BMW B48 / B46 US-spec) and leaves the factory at 302–306 bhp · 450 Nm, ALL4 all-wheel drive, 8-speed ZF automatic. Samuel tunes the F54 Clubman ALL4 (JCW) to the same standard — every map hand-calibrated for the specific car, its fuel grade and its installed hardware, not a base file loaded and left. JCW Clubman ALL4 Stage 1 alone takes it from 302–306 bhp · 450 Nm to 290–330 bhp · 420–470 Nm on the standard turbo, flashed over OBD on BM3, MHD or MG Flasher.
Add the Stage 2 hardware and the JCW Clubman ALL4 targets 330–360 bhp · 470–520 Nm; from there the B48 / B46 (US) stretches to around 420 bhp on a hybrid or big-turbo build with supporting fuelling. Whichever stage suits the JCW Clubman ALL4, the file is delivered within 24 hours and is fully reversible to the supplied stock calibration.

MINI JCW ALL4 tuning — B48 / B46 stages and hardware (F54 Clubman / F60 Countryman)
The later MINI JCW Clubman (F54) and Countryman (F60) ALL4 run the BMW B48 turbo four at ~302–306 bhp from the factory — the strongest-starting MINI four. The heavier body and ALL4 all-wheel drive add drivetrain loss versus the hatch, but the engine makes strong numbers at the crank and responds well to calibration. MINI JCW ALL4 tuning with Samuel focuses on a clean AWD launch and a broad, usable torque curve.
Stage 1
290–330 bhp · 420–470 Nm
ECU/DME software only on stock hardware via the OBD port. Calibrated for clean ALL4 launch and a broad torque curve. 99 RON strongly recommended.
Every MINI JCW ALL4 tune is calibrated individually for the specific car, fuel grade and hardware, and reviewed against your data logs before sign-off.

FAQ
JCW Clubman ALL4 tuning — frequently asked questions
JCW Clubman ALL4 Stage 1 lifts the B48 / B46 (US) from a stock 302–306 bhp · 450 Nm to 290–330 bhp · 420–470 Nm, with no hardware required. The map is flashed through the OBD port on BM3, MHD or MG Flasher and is the starting point for almost every JCW Clubman ALL4 owner — broader torque and sharper throttle response from the factory hardware.
This page covers the F54 Clubman ALL4 (JCW) (F54). They share the B48 / B46 (US) 2.0L turbocharged inline-four (BMW B48 / B46 US-spec) and run the same core calibration, but every JCW Clubman ALL4 tune Samuel delivers is tailored to your exact car, fuel grade and installed hardware — never a base map loaded and left.
Stage 2 on the JCW Clubman ALL4 targets 330–360 bhp · 470–520 Nm and needs intercooler + decat/sports cat + intake (cooler plugs advised). Everything else — turbo, fuel system, intercooler — holds within the Stage 2 figures on the B48 / B46 (US).
On the right hardware spec the B48 / B46 (US) in the JCW Clubman ALL4 reaches around 420 bhp. Stage 1 and Stage 2 run the standard turbo; beyond that needs a hybrid or full big-turbo conversion with supporting fuelling, and the calibration is built bespoke per car.
Remotely. Once Samuel has your build details, the calibrated JCW Clubman ALL4 map is delivered to your flashing tool account (BM3, MHD or MG Flasher) within 24 hours and you flash it yourself over OBD in about 15 minutes. It's fully reversible — the original B48 / B46 (US) stock file is supplied before you flash, so the car can return to factory at any time.
A factory warranty can be voided if BMW shows a tune caused a specific failure, so it's a personal call. Samuel's JCW Clubman ALL4 maps are calibrated to stay within the mechanical limits of the B48 / B46 (US) hardware, and because the tune is reversible to stock before any dealer visit, many owners run a tuned JCW Clubman ALL4 without issue.
