Serving Chester Drivers

Chester BMW & VAG Tuning Specialists

Chester, Hoole, Upton, Boughton and Saltney drivers come to us for the depth of knowledge, from N57/B57 diesels to EA888 petrols and the ZF8, DSG and S-Tronic gearboxes that go with them. We're up the M56 in Warrington, where the dyno does the talking.

Chester sees a lot of premium metal, and we tune it: 640d Gran Coupes, 340i B58s, Audi RS3s and Q5s. Every map is bespoke, validated on our 4WD V-Tech dyno and engine-safe, with a full health check first and your factory file kept on record.

Yes, we offer xHP gearbox software for ZF-equipped BMWs and TCU calibration for VAG DSG/S-Tronic, for sharper, faster shifts to match your engine tune.
