Stage 1 performance figures
Stage 1 gains are different for every engine. A turbocharged petrol car, diesel van and naturally aspirated engine will not respond in the same way.
That's why STX Tuning lists tuning information against specific vehicle and engine records rather than promising the same gains for every car.

Understanding Stage 1
Your vehicle's engine is managed by an electronic control unit, commonly called the ECU. It controls how the engine operates, using information from sensors and the software installed by the manufacturer.
A Stage 1 remap changes selected engine software settings to improve performance on a suitable standard-hardware vehicle.
Depending on the engine, this may involve adjustments to torque delivery, boost control, fuelling and other supported calibration settings.
The result can be stronger acceleration, improved response and more usable pulling power throughout parts of the rev range.
Stage 1 is normally the starting point for customers who want a noticeable improvement without moving straight into major hardware modifications.
However, the available gains and suitability depend on the exact engine, ECU, vehicle condition and calibration.
Stage 1 tuning isn't about chasing the biggest number on a graph. For most drivers, the difference is how the vehicle responds in everyday driving.
Compatible engines can produce more power and torque following a suitable Stage 1 calibration.
The difference may be noticeable when accelerating, joining faster roads or driving through the engine's useful power range.
The increase depends on the exact vehicle.
On supported vehicles, tuning can change how the engine responds to accelerator input.
That can make the car feel more responsive, although the result depends on the existing throttle and torque-management strategy.
Additional usable torque can improve how a vehicle pulls through its working rev range.
For turbocharged engines, this can be one of the most noticeable changes during normal driving.
A Stage 1 remap should match the exact engine and ECU, not just the badge on the boot.
We check the vehicle details before confirming the software options and quoted performance estimates.
The right remap is the one that suits your engine, your vehicle and how you drive.
Both are forms of ECU tuning, but they are designed around different vehicle setups.
The right choice depends on your engine, existing modifications, performance goals and budget.
Stage 1
A practical first step into performance tuning.
Stage 2
A tuning setup planned around supporting hardware.
Not every engine needs the same modifications. STX Tuning will confirm what's appropriate for your exact vehicle before recommending a package.
How your remap works
Getting a Stage 1 remap shouldn't involve guesswork.
We start by checking your vehicle details, explain the available options and confirm the work before arranging your appointment.
Use our vehicle finder or send us your registration, make, model and engine details.
We'll identify the relevant vehicle record and check the available Stage 1 tuning options.
We'll confirm the quoted service, available estimated figures and any suitability checks required for your vehicle.
If there are relevant limitations or existing modifications, these should be considered before the work is agreed.
Choose a Slough workshop appointment or ask about mobile availability for your vehicle and postcode.
We'll confirm the arrangement before booking.
Before tuning, the vehicle's condition and relevant diagnostic information should be considered.
Where suitable, the ECU software work is carried out using the appropriate supported equipment and procedure.
Once the agreed work is complete, the vehicle is checked as appropriate to the service and the results are explained to you.
Any additional findings or recommendations should be communicated clearly.
The cost of a Stage 1 remap depends on the vehicle, engine, ECU and work required.
Some vehicles can be tuned through a supported diagnostic connection, while others may need a different access or software procedure.
Rather than giving every car the same price, STX Tuning lets you find your exact engine and check the available quotation.
Where a verified price is listed, you can see it on that vehicle's product page. If pricing isn't confirmed online, we'll provide a quotation once we've checked your details.
Any additional services or supporting upgrades will be quoted separately unless clearly included in the agreed package.

Real vehicles. Real tuning work.
Stage 1 tuning is available across a wide range of compatible engines. Choose a vehicle below to explore its available software options, performance estimates and pricing.
Figures are catalogue estimates for each exact engine, not measured customer results. Images are illustrative.
A Stage 1 remap is an adjustment to a compatible vehicle's engine ECU software, generally designed to work with standard engine hardware. It can change how the engine delivers power, torque and response. The available results depend on the exact vehicle and its condition.
That depends on the engine. Some turbocharged vehicles have greater tuning potential than others, while certain naturally aspirated engines may see smaller improvements. Use our vehicle finder to view the available estimates for your exact engine. These figures are estimates, not a guarantee of measured results.
Prices depend on the vehicle, ECU and tuning procedure. STX Tuning displays verified vehicle-specific prices where available. Choose your engine to check the listed price or request a quotation if your vehicle isn't priced online.
Suitability depends on the engine, mechanical condition, maintenance history and calibration. A properly considered remap should take those factors into account, but increasing engine performance can place additional demands on components. No remap can guarantee that a vehicle will never develop a mechanical fault.
Stage 1 is generally designed for compatible standard-hardware vehicles. An upgraded intake or exhaust isn't automatically required. The correct setup depends on your engine, existing modifications and the software being considered.
Fuel economy may change, but savings are not guaranteed. Your engine, driving style, journey type and how often you use the additional performance all affect fuel consumption. We would not recommend choosing a performance remap solely on the promise of better MPG.
Appointment time varies depending on the vehicle, ECU access method, software procedure and any checks required. Contact STX Tuning with your registration and we'll explain the expected appointment arrangements for your vehicle.
Some ECU software modifications can be returned to an original calibration where the necessary original software and access method are available. Reversibility depends on the vehicle and procedure. Returning software to standard does not guarantee that manufacturer systems or warranty records will treat the vehicle as unmodified.
An ECU remap is a vehicle modification and should be disclosed to your insurer. Your insurer can explain whether your cover or premium will change. Do not assume your existing policy automatically covers a remapped vehicle.
An ECU software modification may affect warranty coverage, particularly for claims connected to modified components. The position depends on the manufacturer, vehicle and warranty terms. Check the relevant conditions before proceeding.
Many compatible automatic vehicles can be ECU remapped. The gearbox and its torque limits must also be considered. Some vehicles may benefit from a separate gearbox software enquiry, but this is not required or available in every case.
On suitable automatic vehicles, engine and gearbox software may be considered together. Compatibility depends on the transmission and existing calibration. STX Tuning can check the options for your exact vehicle and quote any gearbox work separately.
Gearbox TuningFor suitable vehicles, mobile ECU software appointments may be available in selected areas around Slough. Availability depends on your postcode, vehicle and required procedure. Send us your registration and location for confirmation.
Mobile ECU RemappingStage 1 is generally designed around a compatible vehicle's standard engine hardware. Stage 2 is usually planned around additional supporting components and a matching ECU calibration. The required hardware varies by engine, so Stage 2 is not simply a larger Stage 1 file.
Stage 2 ECU RemappingStage 1 ECU remapping can be available for compatible petrol and diesel engines, but their tuning characteristics and potential gains differ. Select your exact engine to see the available options.
Yes. Send STX Tuning your registration, make, model and approximate year. We'll help identify the relevant vehicle details before confirming the available options.
Stage 1 remapping does not necessarily change exhaust sound. Sound-related calibrations are separate specialist modifications and should be assessed for vehicle compatibility, mechanical risk and applicable road-use requirements.
