xHP Gearbox Tuning Bolton
Official xHP dealer — ranked No.2 worldwide. ZF8 & DCT Stage 1–3 flashed in-house, around 30 minutes from Bolton via the M61 and M6.
Serving Bolton BMW Drivers
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.

In-House 4WD Dyno
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.
