Stage 1 vs Stage 2 — what actually changes

Ask five people what 'Stage 1' and 'Stage 2' mean and you'll get six answers. There's no industry standard — but in our shop the split is simple: Stage 1 is software only, Stage 2 adds the hardware that lets the software do more.

Stage 1: the tune

Nothing gets unbolted. We read your ECU, write a calibration for your car on the dyno, and flash it on. On a typical modern turbo car — Golf GTI, WRX, i30N — that's worth 15–25% more power and torque. The car keeps every piece of factory hardware, which also means it keeps the factory's bottlenecks.

Stage 1 is where the value is. Around $890–$1,490 all-in, same day, nothing else to service or worry about. For most street cars it's also where the fun per dollar graph peaks.

Stage 2: the tune plus the plumbing

Stage 2 adds the parts that were holding Stage 1 back. On most turbo cars that means an intercooler or a downpipe, sometimes both, plus an intake. The hardware lets the turbo move more air and keep it cooler — the tune is then rewritten to use it.

On a Golf R we've seen a Stage 1 deliver +40kW, then Stage 2 take it to +61kW with torque everywhere instead of just at the top. The bigger deal is consistency: a Stage 1 on a hot Queensland afternoon starts heat-soaking and giving power back. Stage 2 hardware holds the number run after run.

What it costs

Our Stage 1 package runs from $1,490. Stage 2 lands around $3,900 depending on what hardware your car needs — the number covers parts, fitting and the full custom tune, so it's two services booked as one. Details are on the price page, and the remap page breaks down what the tune itself involves.

Which one is right for you?

Daily driver you want to enjoy more? Stage 1. You'll feel it every time you merge onto the motorway and it cost less than a decent set of wheels.

Planning to do track days, or the kind of person who'll end up there anyway? Skip to Stage 2 — you'll buy the hardware eventually, and buying it once is cheaper than paying for two separate dyno sessions. If you're still deciding, book a baseline dyno run first. Seeing your car's real curve usually settles the argument in about ten minutes.

The boring caveat

Numbers above are typical turbo-petrol results. Naturally aspirated cars gain much less at Stage 1 — we'll tell you honestly whether it's worth it before you spend anything. That's the whole point of measuring first.
