Start your tune

Tell us the car. We'll do the rest.

Ordering is free and takes about three minutes. The hour starts when your stock file reaches us, and you only pay once the finished calibration is sitting on your order page. Nothing here commits you to anything.

Your car

Paste your VIN and we'll fill in the rest, or just type the make and model. The VIN is the more reliable route — it pins down the exact engine and ECU, which is what decides how we tune it.

VIN (recommended) We use it to decode the year, engine and ECU. It is stored with your order and nothing else.

Make Tell us the make. Model Tell us the model. Year

Engine If you know it. We can work it out from the file otherwise. Your tool Whatever you used to read the car.

Your build

Tick everything actually fitted to the car right now — not what you plan to fit. The calibration is written around your real hardware, so an extra tick here is the difference between a tune that fits and one that doesn't.

Fuel you'll run Tune it for the fuel you'll actually put in it. Anything else we should know Faults included — we'd rather know.

What do you want from it? Plain English is perfect. This goes straight to your tuner.

Pick your stage

Match it to the hardware you ticked above. Not sure? Pick the one you think fits — your tuner checks it and tells you before you pay anything, so there is no way to get this expensively wrong.

Your files

The stock read is required — it is both what we tune and your backup, and we archive and hash-verify it before anyone touches a map. The datalog is optional but it is the single biggest thing you can do to get a better first file.

Your stock calibration *

Read out of the car, before any changes. Click to choose, or drop it here.

We need your stock file to tune anything.

A datalog of a drive

A few minutes of normal driving plus one full-throttle pull. Strongly recommended.

Don't know how to pull either file? The guide walks you through both reads step by step — it takes about ten minutes the first time. You can also start this order now and send the files in the chat on your order page; the hour simply starts when they land.

Where to send it

We email you the moment your tune is ready, and your order page lives at a link tied to this address. Use one you actually read.

Your name We need a name to put on the order. Email That email doesn't look right — check it, it's how you get your tune.

WhatsApp (optional) Fastest way for your tuner to reach you mid-build. Country (optional)

Before we start

Three things we need you to have read. They are short, and they are the ones that matter.

Please tick all three to continue.

You'll pay, after delivery —pick a stage above

No card required now. We build your tune first, and the invoice only appears once the finished file is waiting on your order page.

Your stock file is archived and hash-verified before anyone opens a map.

Two tuners are on shift right now, whatever time it is where you are.

Three revisions included free, each turned around inside the hour.
