Identify your A3 before comparing tunes
Find the model year, factory power and gearbox type if you know them. A build sheet, original sales paperwork or a dealer parts enquiry can help confirm the variant. If you’re unsure, start with the registration and tell us what you know. Browse Audi in the Vehicle Finder.
If the car already has a remap, or the ECU has been replaced or updated, tell us before we quote. The ECU on the car today is what we need to identify.
Compare the same engine and setup
When reading a quoted gain, check whether it refers to the 150 or the 184, whether it’s an estimate or a measurement, and what hardware was fitted. If the figure came from a dyno, ask whether it’s wheel output or an estimate at the engine. Our dyno and mobile remapping guide explains how to read a chart.
Tell us how the car feels in normal driving. If you want better response on an incline or fewer downshifts at cruising speeds, that helps frame the conversation about what’s suitable. We’ll check the engine and gearbox before discussing what to expect.
What to check on an older A3
Share the mileage and service history. Mention warning lights, increased smoke or clutch slip. If it’s an automatic and you’re also considering a gearbox tune, tell us about recent servicing and how it shifts. Our high-mileage remap guide explains when to investigate symptoms first.
