Serving Bolton BMW Drivers

xHP For Bolton BMWs

Bolton BMW drivers are around half an hour from one of xHP's top-ranked dealers worldwide, currently No.2. Every ZF8 and DCT flash happens in-house at our Warrington workshop, usually while you wait.

Whether your 330d shifts lazily or your M135i deserves launch control, xHP transforms the gearbox, and pairs perfectly with a Stage 1 engine remap on our 4WD dyno in the same visit.

What xHP Unlocks

Transform How Your BMW Shifts

xHP rewrites the gearbox software — Stage 1, 2 and 3 profiles for the ZF8 and DCT.

Faster, Sharper Shifts

Dramatically reduced shift times across all modes, Sport and manual become genuinely responsive.

Raised Torque Limits

Factory TCU limits raised so the gearbox properly handles a Stage 1 or Stage 2 engine tune.

Launch Control & Manual Mode

Proper launch control and a true hold-your-gear manual mode, plus custom shift maps.

In-House 4WD Dyno

Engine + Gearbox, Proven Together

Pair xHP with a Stage 1 remap and the whole package is validated on our V-Tech 4WD linked dyno.

The engine map adds the torque, xHP raises the gearbox limits to use it. Doing both together on our V-Tech 4WD linked dyno means the whole drivetrain is proven as one, with a before-and-after printout to take away.
