STX Tuning performance build studio

Performance tuning packages & upgrades

Your car. Your goals. Your performance build.

Combine suitable intakes, intercoolers, exhausts, turbo upgrades, ECU tuning and fitting into one planned build, instead of contacting several businesses separately.

Find your engine, choose a starting package and customise it. STX Tuning in Slough checks compatibility and sends one complete quotation.

Start with your exact engine.

Different cars need different components. Choose your vehicle so your package is built around the real engine.

Can't find your engine?

Send STX Tuning the registration, make, model and year so we can help identify the right vehicle.

One performance build. One clear enquiry.

  • Vehicle-specific options

    Choose suitable upgrades for your exact engine.

  • Parts & software

    Explore hardware alongside ECU and gearbox tuning.

  • Slough workshop

Choose your performance build.

Every car and driver is different. Some customers want a simple intake and ECU package, while others are planning a complete turbocharged performance build.

Choose the starting point that sounds right for you, then customise it around your actual engine.

What makes a complete performance package?

A package is not a universal parts list. It is a set of components and services that suit the actual engine, the parts already fitted and what you want the car to do.

Hardware and ECU software are planned together, so the calibration suits the setup and nothing is quoted that your car doesn't need.

Every component is checked for fitment and availability before your quotation is confirmed.

  • ECU tuning

    Stage 1, Stage 2 or custom software matched to the hardware.

  • Air intake / induction kit

    Vehicle-specific intake hardware where available.

  • Turbo inlet

    Inlet components between the intake and turbocharger.

  • Intercooler

    Charge-air cooling for suitable turbocharged engines.

  • Charge / boost pipes

    Boost hoses and charge pipes where relevant.

  • Sports exhaust

    Cat-back, valved or resonated systems.

  • Downpipe hardware

    Sports-cat downpipe options; emissions equipment stays on road cars.

  • Hybrid / upgraded turbo

    For more involved builds with custom calibration.

  • Fuel-system components

    Only where the engine and target genuinely call for it.

  • Gearbox software

    TCU tuning for compatible automatic transmissions.

  • Clutch / drivetrain

    Considered when torque changes on suitable vehicles.

  • Workshop fitting

    Installation at the Slough workshop.

Package families explained.

Stage 1 hardware packages

Stage 1 ECU software is designed for suitable standard-hardware engines. Optional intake hardware can be added where a product exists for your car. Software-only remaps start on the Tuning Packages or Stage 1 pages.

Stage 1 remapping

Stage 2 hardware-inclusive packages

Stage 2 considers supporting hardware alongside suitable software. Tell us what's fitted and we quote only the parts you actually need. There is no universal Stage 2 list.

Stage 2 hardware checklist

Exhaust & sound packages

Cat-back, resonated and valved systems change the character of the car. Sound and noise must stay appropriate for road use, and emissions equipment stays on road vehicles.

Exhaust upgrades

Hybrid turbo packages

A hybrid turbo is part of a wider build: cooling, intake, exhaust, fuelling, drivetrain and custom calibration are all considered. Fitting is workshop-only in Slough.

Turbo upgrades

ECU & gearbox combinations

Compatible automatic gearboxes may have separate TCU software. Manual gearboxes are never offered automatic gearbox tuning; clutch capability is considered instead.

Custom remapping

Performance manufacturers to explore.

Tell us which manufacturers you prefer. These are examples of names customers ask about, not a stock list or an authorised dealership claim. Availability and fitment are checked for your exact car.
