Find Your Tuning Option

One ladder, five levels — from a balanced Stage 1 remap on stock hardware all the way to a full Stage 5 race build. Plus diesel torque tuning and a full set of Tuning+ software solutions.

Every option is prepared in-house from your original ECU file and matched to your exact vehicle, hardware and goal — never a generic map.

The stage ladder

From daily power to full race build

Each level adds capability. Stage 1–2 are software (and supporting parts); Stage 3–5 are full hardware builds. We confirm what's realistic and road-legal for your vehicle first.

Diesel / TDI tuning

Running a diesel? The ladder still applies, but diesel tuning is built around torque — stronger pulling power and mid-range response for everyday driving and towing, rather than peak headline figures.

How to choose

Not sure which level?

Three things decide the right tuning option — we confirm them with you before any work.

  1. 01
    Your hardwareStock points to Stage 1; bolt-ons open Stage 2; a build opens Stage 3–5.
  2. 02
    Your fuel & enginePetrol or diesel, and the engine's condition, shape the calibration.
  3. 03
    Your goalDaily drivability, track performance or full race — we match the level to it.

Special software solutions such as DPF, EGR, AdBlue or OPF are only carried out where they are legally permitted for your vehicle and use. If you're unsure what's allowed, contact our team before booking.
