VIEZU are Audi tuning specialists offering custom ECU remapping and performance tuning for the full modern Audi range, from the A1 through to the RS6 and R8. As Audi performance specialists we write every Audi remap file in house, develop it on our own rolling road and tailor it to the exact engine and gearbox in front of us rather than pulling it from a generic file library. We work with both retail Audi owners and professional tuners through our trade and dealer network, and all work is covered by our money back guarantee and supplementary insurance backed warranty.
Custom Audi ECU Remapping
Audi builds some of the most tuneable engines on the road. The turbocharged TFSI petrol units and the TDI diesels both respond well to a properly developed map, and the gains are usually larger than most owners expect. The reason is simple. Manufacturers leave a deliberate margin in the factory calibration to allow for varying fuel quality, climate, service intervals and emissions targets across every market the car is sold in. Good Audi tuning recovers that margin safely.
Our Audi ECU remap work is carried out through the OBD diagnostic port wherever the ECU allows it, which keeps the process quick and clean. Where an ECU is locked, the file is read on the bench instead. Either way the map is custom written for your car, so a very specific calibration can be produced for your goal, whether that is all out Audi performance tuning or improved fuel economy on a daily driver. The same custom approach applies across Audi diesel vehicles and Audi petrol models alike.
Audi chip tuning, the older term many people still search for, has largely been replaced by ECU remapping. The principle is the same, you are changing the software that controls the engine, but a modern Audi remap is far more precise than the chip swaps of twenty years ago. All remapping is a form of car tuning, though not all car tuning is remapping. Tuning is the broader term and can include physical hardware changes, while remapping refers specifically to reprogramming the ECU software.

What Audi Stage 1, Stage 2 and Stage 3 Tuning Means
The staged system is the standard way the tuning industry describes how far a build goes. It runs in a clear order and each stage assumes the one before it.
An Audi Stage 1 remap is software only. There are no physical changes to the car. The map works within the limits of the standard hardware and is developed to safely improve power and torque while keeping the factory components and reliability intact. For most Audi owners this is the sweet spot, more performance and sharper throttle response with no extra parts to buy.
An Audi Stage 2 remap combines software with moderate hardware upgrades. Typical Stage 2 parts on an Audi include a high flow air filter or intake, an upgraded intercooler and a less restrictive exhaust or downpipe. The map is then developed to suit those changes, so the hardware and the software work together.
An Audi Stage 3 remap is a significant hardware overhaul, often involving a hybrid or larger turbo, uprated injectors and fuelling, and supporting cooling work. This is specialist territory and the map has to be written specifically for the build. Stage 3 figures on the right Audi platform can be dramatic, but the work needs proper development and measurement to stay reliable.
Whatever stage you are considering, the only accurate way to know your true starting power and your gains is on a rolling road in-house dyno. Online BHP calculators and plate based estimates are the least accurate method because they work from broad averages and ignore the actual condition of the engine. A dynamometer measures what the car is genuinely producing.
Audi Performance Tuning and Economy Tuning
Not every Audi owner is chasing outright power. Our performance tuning maps focus on power, torque, throttle response and overall driveability, which is what most people want from an S or RS model. Our economy tuning maps take the opposite priority and optimise the engine for efficiency, which can be worth real money over a year on a high mileage diesel.
For the TDI diesel range specifically, our diesel tuning covers the full lineup. A point worth raising here for any owner researching diesel mods, removing or deleting emissions hardware such as a DPF or EGR is not legal for road use in the UK. We always recommend legal options first, for example a proper DPF clean rather than a delete, so the car stays road legal and passes its MOT.
Audi models fitted with the DSG or S tronic automatic also benefit from matching gearbox tuning. Raising engine torque without addressing the transmission software can leave the gearbox holding the car back or behaving oddly under load, so the two are often best done together. Audi’s dual clutch transmissions, badged S tronic and built on the wider Volkswagen Audi Group DSG platform, are among the most commonly tuned gearboxes in the trade, which is one reason so many workshops treat Volkswagen Audi Group specialists as a category worth building a business around.

Audi Tuning for the Trade
A large part of what VIEZU does is supply and support professional tuners rather than only tuning cars directly. If you run a workshop or you are setting up a remapping business, the Volkswagen Audi Group is one of the most profitable platforms you can specialise in, simply because there are so many of them on UK roads and owners actively look for tuning.
We supply the hardware to read and write Audi ECUs, including the Alientech KESS3 and the Magic Motorsport FLEX, the latter being particularly strong for the DSG and S tronic gearbox work that VAG cars demand. Newcomers to the trade usually start with a business start up kit that bundles the tool, protocols, training and file credits together so you can start earning from day one.
If you would rather not write files yourself, our custom tuning files service gives you access to our file writing team seven days a week, with Audi maps developed and proven in house. The service runs from 7am every day including weekends, and the average custom file comes back in around twenty minutes with a maximum wait of one hour even at peak times. For a standard Stage 1 Audi file, the target turnaround is thirty to sixty minutes, so a car on the ramp on a busy Friday afternoon does not tie up your workshop. There is more on this in our guide to custom versus generic tuning files. And if you want to build the skills properly, our tuning training courses cover the tools and software hands on.
Every Audi map, retail or trade, is backed by our supplementary insurance backed warranty against component failure. VIEZU is one of the only providers in the industry to offer this, and it gives both you and your customer protection that generic file suppliers do not.

Audi Tuning Specialists FAQs
What company tunes Audis?
Plenty of companies offer Audi remaps, but they fall into two groups. Some flash a generic file bought in from elsewhere, others develop their own software in house. VIEZU sits firmly in the second group. There is no single best Audi tuning specialist for every car, but if you want maps written and tested in house, full coverage of the modern range and a money back guarantee, we are the perfect choice. As an Audi tuning specialist UK owners and trade customers come back to, we also supply and train professional Audi tuners across our worldwide dealer network.
What is a Stage 1 Audi tune?
An Audi Stage 1 tune is a software only remap. No parts are changed. The map is developed to safely raise power and torque within the limits of the standard hardware, improving performance, throttle response and often economy while keeping the car reliable. It is the most popular option for everyday Audi owners because it delivers a noticeable difference with nothing extra to buy or fit.
What is a Stage 2 Audi tune?
An Audi Stage 2 tune pairs the remap with moderate hardware upgrades, typically a high flow air filter or intake, an upgraded intercooler and a freer flowing exhaust or downpipe. The software is then written to match those parts. Stage 2 gives more power than Stage 1 and is a sensible step for owners who want a stronger car without going to a full Stage 3 build.
What is a Stage 3 Audi tune?
An Audi Stage 3 tune involves major hardware changes such as a hybrid or larger turbo, uprated injectors and fuelling, and supporting cooling upgrades, with a map written specifically for that exact build. It produces the biggest gains but needs proper development and rolling road measurement to remain reliable, which is why it is best handled by a specialist.
What makes VIEZU Audi VAG group tuning specialists?
VIEZU has spent over fifteen years developing tuning for the Volkswagen Audi Group platforms, both as a tuning house and as a supplier to the trade. We develop Audi maps in house on our own rolling road, support the DSG and S tronic gearboxes that VAG cars commonly need, and supply the tools, files and training that other professional VAG specialists rely on. That combination of direct tuning experience and trade level expertise is what makes us specialists rather than resellers.
Will an Audi remap affect my warranty or insurance?
If a car is modified, the original manufacturer warranty may be affected, and a manufacturer can refuse to cover drivetrain components if a modification is detected and proven to be the cause of the issue. VIEZU offers its own supplementary insurance backed warranty to cover against component failure, which is a key reason owners and dealers choose us. You should always inform your insurance provider of a remap, as failing to declare a modification can affect a claim.
