Why choose a workshop tuning appointment?

Mobile ECU remapping can be convenient for suitable software procedures.

But not every vehicle or tuning project is appropriate for a mobile appointment.

A workshop visit can be a better option where the job involves additional equipment, supporting hardware, more involved checks or a specialist setup.

A physical location you can visit

STX Tuning has a workshop base in Slough, so you can discuss an appropriate tuning appointment at an actual premises rather than arranging every service remotely.

Suitable for more involved work

Performance hardware, more specialised ECU procedures and combinations of software and fitting work may need a workshop appointment. The correct facilities and process depend on the specific vehicle and agreed work.

Discuss software & hardware together

If you're planning Stage 2, gearbox tuning or additional engine upgrades, it can be useful to review the complete setup before booking.

Clearer planning before work begins

Vehicle details, existing modifications, available tuning figures and the proposed work can be checked before confirming the appointment.

What can you book at the STX Tuning workshop?

From straightforward ECU remapping enquiries to more involved performance upgrades, the right appointment depends on what you drive and the work you're considering.

Explore the options below and tell us which services you'd like included in your quotation.

Stage 1 performance remapping

Stage 1 ECU remapping is generally intended for compatible vehicles with standard engine hardware.

On supported engines, it can improve power, torque and throttle response.

Check the available figures and price for your exact vehicle before arranging an appointment.

Stage 2 performance tuning

Stage 2 ECU tuning is planned around suitable supporting hardware and an appropriate calibration.

The required components vary between vehicles, so a proper quotation needs to consider the engine and any parts already fitted.

Explore Stage 2

Gearbox software tuning

On suitable automatic vehicles, TCU software may change supported shift and torque-management characteristics.

Options vary between DSG, S Tronic, ZF and other transmission families, so compatibility must be checked.

Explore gearbox tuning

Custom tuning for modified cars

Already running an upgraded intake, intercooler or turbocharger?

More involved setups may need additional compatibility checks and a tuning quotation that considers the actual hardware fitted.

Explore custom ECU tuning

Intakes, intercoolers & performance upgrades

Supporting hardware may be relevant when planning a higher-performance build.

STX Tuning can discuss compatible performance parts and fitting services for suitable vehicles.

Explore performance upgrades

Petrol & diesel remapping

Petrol and diesel engines respond differently to ECU tuning.

Whether you drive a turbo petrol performance car or a diesel car or van, the available software and gains depend on the exact engine.

Images are illustrative.

Should you visit the workshop or book mobile remapping?

Both types of appointment can have their place.

The important factor is what work your vehicle actually needs.

Before you bring your car to the workshop.

A little information before your appointment helps us understand the vehicle and the work you're considering.

You don't need to know every technical detail. Send us what you have and we'll explain if anything else is required.

  • Your registration

    Have your registration available so we can identify the vehicle.

  • Your tuning goal

    Tell us whether you're looking for stronger performance, more usable torque, gearbox tuning or additional upgrades.

    Let us know about any intake, intercooler, turbocharger, exhaust or ECU software changes already fitted.

  • Warning lights or running issues

    If the vehicle has any warning lights, misfires, boost problems or abnormal behaviour, tell us before booking. These may need to be assessed before additional performance tuning is appropriate.

  • Fuel requirements

    Some petrol tuning calibrations require a particular fuel grade. We'll confirm any applicable requirement for your vehicle.

  • Appointment confirmation

    Please arrange and confirm an appointment before travelling, so we can discuss the required work and availability.

Don't make an unnecessary journey. WhatsApp your vehicle details first.

    STX Tuning were absolutely brilliant. The service was super fast — same day turnaround — and they solved an issue with my car that a main dealer claimed would cost me thousands to fix. It turned out the expensive repair wasn’t even necessary, and STX handled it quickly and professionally. Honest, efficient, and highly recommended!

    STX were great! (its within ONYX which confused me when I got there, no biggy, just for anyone else reading it). I happened to be arriving when a guy must have been starting their shift, super helpful and got me to the right person. On the way in they even took the time to show my son the Lambo they had, this type of service is so nice to receive. The young guy we spotted fitting the wheels later on, thank you! In for a Stage 1 remap, all done in 30 minutes, and car drives brilliantly and exceeded expectations. Also at a great price as well. All staff I met were super nice and helpful. Credit to you guys! I will definitely be choose these guys going forward! Highly recommend.

    Went to remap my GLE 250d and the whole process was smooth from start to finish. Super responsive, and had the job done quickly with zero hassle. The results are brilliant , noticeable power gains straight away and smoother drive overall. Would highly recommend them to anyone looking for a quality remap with excellent customer service!
