ECU Remapping Bolton
BMW & VAG tuning for Bolton drivers — dyno-developed maps with real figures, an easy run down the M61 to our Warrington workshop.
Serving Bolton Drivers
Bolton, Horwich, Westhoughton and Farnworth drivers choose us because the work is provable — every map is built and verified on our 4WD linked V-Tech dyno, and you leave with the numbers to prove it. We're down the M61 and round the M60, well worth the trip for a job done right.
From a sensible 320d daily to an M135i hot hatch or an Audi S4, we tune the lot. Each file is custom-written, health-checked beforehand and fully reversible — so you get sharper response and stronger mid-range without gambling on a generic map.
What We Offer
Every job is read, mapped and proven on our in-house 4WD dyno.

In-House 4WD Dyno
Every map is developed and validated on our own V-Tech VT-4 4WD rolling road — no guesswork, just real, measured figures.
From Bolton it's a straightforward run, and worth it for a map developed on our in-house V-Tech 4WD linked dyno rather than guessed at. Four driven wheels means xDrive and Quattro are tuned safely, with the gains measured on a back-to-back run.
