Basic checklist before you tune

  1. Service history & mechanical fitness (*** leaks, proper cooling)
  2. Quality intake & exhaust path — inspect for restrictions
  3. Tire condition and brake health — essential for safety testing
  4. Map your goal: economy, track, or balanced street use

A pre-tune mechanical inspection saves wasted tuning sessions and prevents costly engine damage.

Aftermarket parts: what to prioritise

Choose parts that match your tuning target and maintain compatibility with emissions/legal requirements in Australia.

Component When to fit Notes
Air filter/intake Stage 1 Improves response; ensure mass‑air sensor compatibility
Cat-back exhaust Stage 1–2 Check local RWC/N.OISE rules for your state
Intercooler upgrade Turbo cars, Stage 2+ Reduces knock risk on higher boost
Fuel system (injectors/pump) High-power builds Required for safe fuelling at target power
Selection of tuning parts

Prioritise cooling and fuelling early — they underpin safe power increases.

Dyno tuning: what to expect

Book time on a 4WD dyno for AWD and 2WD cars. Expect logging runs, iterative mapping, and a final verification sheet showing gains and AFR targets.

  • Bring fuel and planned hardware list
  • Allow 2–4 hours depending on scope
  • Ask for a torque and power graph export

Safety and Australian legal notes

Always check your state regulations (RMS/NRMA, VicRoads, QLD Transport) before installing parts that affect emissions or noise. Keep documentation for any ECU changes and ensure your car remains roadworthy.

  • Aftermarket exhausts may fail noise checks — request test certificates
  • ECU remaps: keep original tune backed up and request a copy of the new map
  • Insurance: inform your insurer of modifications to maintain cover

Common questions

Yes — reputable tuners keep a backup of your original map. Always request that backup on USB or cloud storage.

Stage 1 gains vary by platform; typically 10–25% on turbo cars, less on naturally aspirated engines. Dyno verification is the only reliable measure.

Not usually for modest tunes. Monitor AFR and fuel trims; if running rich/lean at target power, upgrading injectors or pump may be necessary.

Resources & next steps

Local dyno shops

We recommend booking a pre-tune inspection and dyno slot together to save time and ensure correct baseline logging.
