Car Tuning Chelsea Heights.
Independent. Specialist. Fair.

A modern turbocharged European car's ECU is not tuned aggressively from the factory. Emissions regulation, worldwide fuel-quality variability, and warranty exposure force the factory calibration into a very conservative window. A well-executed Stage 1 flash respects the mechanical limits of the engine while opening up the calibration to what the hardware is genuinely capable of on Australian 98 octane or E-blend.

Typical Stage 1 gains — BMW N55/S55/B58: 60–120 hp. Audi EA888 gen3: 80–140 hp. VW Golf R/GTI: 60–120 hp. Porsche 991.2/992 turbo: 80–150 hp. AMG M139: 60–120 hp. These are real, sustained gains — not one-run headline numbers.

Every tune is datalogged. Knock detection, timing, boost, AFR, MAF, fuel trims — logged under load before the car leaves. Backup files stored. Where the platform supports it (MHD, bootmod3, COBB, EcuTek, some APR builds), dealer-mode return is available for warranty visits. We're honest about warranty implications up front.

Stage 2 is not 'a bigger map'. It's a supporting-hardware package plus a matched calibration. Downpipe (or catless downpipe), intake, intercooler, high-flow fuel pump — installed correctly and calibrated to match. A Stage 2 map on a Stage 1 car is guaranteed to make less power and often less reliable than a well-executed Stage 1.

We calibrate to the actual hardware fitted, not a generic 'Stage 2' file. Bespoke calibration is available for standalone and factory-ECU platforms where it is warranted — usually anything above Stage 2 or on unusual fuel combinations (methanol injection, race blend, port injection retrofits).

• Fuel and AFR

  98 octane vs E30/E60/E85 changes calibration entirely. Correct AFR for the fuel and load window — not a generic target.

• Knock margin

  Non-negotiable. Every tune leaves the workshop with measured knock headroom under WOT — logged and stored.

• Turbo & wastegate behaviour

  Boost control PID tuned to actual hardware — not a flat-line request that overshoots and cuts.

• Transmission tune (TCU)

  For DSG/DCT/ZF 8HP — matched to engine tune. Torque limiter raised, launch RPM raised, shift firmness set.

• Data storage

  Every tune backed up. Original factory file, current tune, all revisions — stored on our systems, provided to you.

• Warranty conversation

  Every platform is different. We tell you honestly what a dealer will and won't detect before we tune.

The workshop is in Wantirna South, VIC 3152 — approximately 30 minutes from Chelsea Heights (3196). Most clients drop the car in the morning and arrange their own transport back to work or home. Send your rego or VIN through the quote form or call 0483 939 216 — we come back with a written, line-itemised quote same business day.

Same-day work where possible. Anything requiring parts on order gets a realistic in-and-out timeline before you book. No 'we'll let you know' — you get a scheduled collection day.
