Gearbox Tuning Derby

Faster shifts. Higher torque limits. · £280 – £450 · 60–90 minutes

Your gearbox has a computer too — and it's just as capped as the engine ECU. A TCU (Transmission Control Unit) calibration rewrites shift maps, torque limits, clutch pressures and — on many platforms — unlocks launch control that was disabled by the factory. The result is a car that shifts like it was engineered to a much higher spec.

In Derby we come to you — Chaddesden, Alvaston, Mickleover, Allestree, Littleover, Spondon and every DE1, DE3, DE21, DE22, DE23, DE24, DE72, DE73, DE74, DE75 postcode along the A38, A50, A52, A6 and M1 junction 25. Same fixed price wherever you are in Derbyshire.

Which gearboxes do you tune?

VW/Audi DSG (DQ200 7-speed, DQ250 6-speed, DQ381/500 7-speed), Porsche PDK, BMW DCT (M2/M3/M4), ZF 6HP and 8HP (BMW, Range Rover, Jaguar), Mercedes 7G-Tronic and 9G-Tronic, Ford Powershift. Others by request.

Why tune the gearbox as well as the engine?

Because factory gearbox torque limits are often the true bottleneck. A Stage 2 engine map can make more torque than a stock TCU will allow the box to deliver — the gearbox will clutch-slip or de-torque under load. A matched TCU calibration lets you use every last Nm.

Is a TCU remap safe?

Yes when calibrated correctly. We stay within the mechanical hardware limits of your specific gearbox — that's why we won't do a Stage 3 TCU on a stock DQ250 with a poverty-spec clutch pack. We tell you honestly what your box can and can't handle.

Gearbox Tuning across Derby

Derby is an engineering city, and Derby drivers ask better questions than most — about torque curves, EGT limits and what the data-log actually shows. We like that. Daily commuters on the A38 and A50 want a Stage 1 that fills in the mid-range and settles the DSG or 8-speed auto; tradespeople in Sinfin, Alvaston and Spondon want their Transporter or Vivaro to pull properly when loaded; and performance owners in Allestree, Mickleover and Darley Abbey want Stage 2 calibrations with hardware-matched boost and logged proof of the result.

◉ The process

How mobile remapping works in Derby

01

Fixed quote from your reg

Send your registration by WhatsApp, phone or the booking form. You get a fixed, vehicle-specific price for Derby — not a 'from' figure that climbs on the day.

02

We come to you

We arrive at your home, workplace or yard anywhere in Derby with genuine, licensed tuning tools (not clone hardware) and a professional data-logger.

03

Pre-map health check

Full OBD diagnostic scan and live-data baseline log. If the DPF, EGR, turbo or sensors show a problem, we tell you before writing anything.

04

Read & archive your original file

Your factory ECU file is read and archived securely so the car can be returned to stock at any time — before a dealer visit or when you sell.

05

VIN-specific calibration written

The remap is written for your exact ECU, engine and hardware — fuelling, boost, torque limiters and timing adjusted within safe factory tolerances.

06

Logged verification drive

A post-map road test on local Derby roads with live data-logging. You see the before/after figures and we check knock, EGTs, boost and fuel trims are all where they should be.

Stage 1 results

Before & after: what we see on Derby cars

Manufacturer stock output vs our typical Stage 1 calibration for each platform. Indicative figures — every car is health-checked and verified with a live road data-log, and your before/after numbers are shown to you on the day.

◉ FAQ

Gearbox Tuning Derby — FAQ

Will a TCU remap affect gearbox reliability?

Not when written within the mechanical limits of your specific box and clutch pack. We calibrate conservatively for daily-driven cars.

Can I get launch control on my Golf R?

Yes — factory launch control is available with our DSG map and is fully refined for street use.

Do you tune torque converters like the ZF 8HP?

Yes — the ZF 8HP responds beautifully to a proper TCU calibration; a favourite platform of ours.
