Key takeaways An engine remap can push more torque through a gearbox than it was designed for. A gearbox tune changes shift speed, clutch pressure and torque limits, and should match the engine tune. Tuners quote different torque limits for each type of DSG, so find out which gearbox your car has. Fluid changes matter even more once the car is tuned. Most people think of chiptuning as an engine job. But if your car has an automatic or DSG gearbox, that gearbox has its own computer, and it has to cope with the extra power too. What a gearbox tune changes A gearbox remap, often called a TCU tune, adjusts how the gearbox behaves. Tuners say it can raise the torque limit, change shift speed and timing, increase clutch pressure so the clutches do not slip, and alter launch and gear selection. The result is meant to be a gearbox that suits the new engine settings. Why it matters If you tune only the engine, the extra torque can make the clutches slip and wear faster. The gearbox computer...

Key takeaways A remap can improve economy on some turbo diesels, but it is never guaranteed. Auto Express reports claims of 7 to 10 per cent on turbo diesels, and warns that economy can also get worse. Any saving disappears if you use the extra power often. Do not tune for fuel savings alone. Measure your own MPG before and after. Some tuners promise more power and lower fuel bills at the same time. It sounds too good to be true, and sometimes it is. Here is when a remap can save fuel and when it will not. Why a remap can save fuel Factory settings are a compromise between power, emissions, smoothness and cost. A good remap can add torque at low revs, so the engine does less work to hold a speed. You can stay in a higher gear for longer and use less throttle to pull away. On diesels, adjusting injection timing and pressure can also help the engine burn fuel more completely when cruising. This is why most economy claims come from turbo diesels, where Auto Express reports figures of ...

Key takeaways Whether a 911 benefits from a remap depends mostly on the engine: turbocharged models respond, naturally aspirated ones barely do. Gains on a car this well engineered come with real trade offs in heat, drivetrain load and resale value. Warranty, insurance and Porsche specialist experience matter more here than on a typical car. Check the car's condition and service history before changing any software. The Porsche 911 is one of the most carefully engineered sports cars on the road, so it is fair to ask whether it needs tuning at all. The honest answer is that it depends on which 911 you own. Some engines have a lot of room in their software, others very little, and the way you use the car matters as much as the numbers. Turbocharged or naturally aspirated? This is the most important question. Turbocharged 911s, such as the Carrera models from the 991.2 generation onward and the Turbo versions, can respond well to a quality remap, because the software controls boost pr...

Key takeaways Chiptuning is not illegal in itself, but the car must stay compliant with local rules. Emissions equipment such as the DPF, EGR and AdBlue system must stay in place and working. Tell your insurer about the change, or a claim could be reduced or refused. Rules differ by country, so check with your inspection centre before tuning. Many drivers assume that a remap is just a software update and therefore nobody needs to know about it. In reality, changing how an engine performs can have legal, insurance and inspection consequences. This guide explains the main points, using the European situation as a general reference. Rules vary from country to country, so treat this as an overview and not as legal advice. Is chiptuning legal? Modifying a car is not illegal in itself, but the vehicle has to remain compliant with the rules that apply to it. Cars are approved with a specific power output and emissions level, and in many countries a change that affects either of them has to be...

Key takeaways There is no single price: it depends on your car, the type of tune and who does the work. Budget for costs people forget, not only the headline remap fee. The cheapest option can cost far more in repairs than it ever saved. Value depends on your car and how you drive, so decide before you pay. Price is usually the second question after "will it work?". The honest answer is that there is no single figure, because the cost depends on your car, the type of tune and who does the work. What you can do is understand what drives the price and judge whether the result is worth it for you. What affects the price The type of tune: a software remap, a tuning box and a custom tune made on a dynamometer are very different services, and the price rises with the amount of work and testing. Your engine: popular engines are well known to tuners and are often cheaper. Rare or complex ones can cost more. The stage: Stage 1 is software only. Stage 2 and higher also involve hardw...

Key takeaways A remap does not automatically cancel your warranty, but cover can be refused for related faults. A remap can sometimes be detected, even if the original software is restored. A tuner guarantee is not the same as the manufacturer warranty. Ask the right questions before you tune and keep all paperwork. If your car is still under warranty, the first question about chiptuning is almost always the same: will I lose my cover? The honest answer is that it depends, and it is better to understand the risks before you book a remap than after something goes wrong. What a warranty actually covers A manufacturer warranty covers defects in materials and workmanship. It does not usually cover damage caused by modifications. If a modified engine or gearbox fails, the manufacturer may ask whether the tune could have contributed, and it can refuse the claim if it believes that it did. Can a remap be detected? Many tunes leave traces in the engine software, and a dealer can often tell tha...

Key takeaways The A45 AMG is already very powerful, so a remap adds performance but also stress. Gains depend on the exact engine, fuel quality and supporting hardware. Choose a specialist with real experience of AMG engines and ask about their guarantee. Think about warranty, insurance and reliability before you tune.  The Mercedes A45 AMG is already one of the most powerful compact hot hatches ever built, and its 2.0 litre turbo engine is a favourite among tuners. A remap can make it feel even more aggressive, but this engine runs close to its limits from the factory, so the details matter. The cars in short First generation (2013 to 2018): a 2.0 litre turbo four cylinder with all wheel drive (4MATIC) and a dual clutch gearbox. Output was around 360 hp at launch and around 380 hp after the 2015 update. Second generation (A45 and A45 S): a newer 2.0 litre turbo engine, with roughly 390 hp in the A45 and around 420 hp in the A45 S. Figures can vary by market and model year,...

Key takeaways Who does the remap matters far more than the brand of the software. A poor tune can cost you performance, reliability and money. Ask these eight questions before you pay and compare more than one workshop. Get the guarantee and the work description in writing.  The quality of a remap depends far more on who does it than on the brand of the software. A poor tune can cost you performance, reliability and money, so it is worth taking a little time to choose well. These eight questions will help. 1. Do you have experience with my exact engine? Engines in the same family can behave very differently. A workshop that regularly tunes your model will know the safe limits and the common weak points. 2. Is the tune made specifically for my car? Some workshops simply load a generic file. A better approach is a file adjusted to your car’s software version, mileage and condition. 3. Can you show me dyno results? A power measurement before and after shows what was really gaine...

Key takeaways Turbo diesels are popular tuning candidates because they make a lot of torque. Gains are real but limited by the engine, turbo and clutch. Keep the DPF, EGR and AdBlue system in place and working. Avoid common mistakes: cheap generic tunes, ignoring servicing and chasing big numbers.  Diesel engines are among the most common candidates for tuning. They produce lots of torque, they are usually turbocharged, and the software offers a lot of room for adjustment. But diesels also have parts that need extra care. Why diesels respond so well Most modern diesels have a turbocharger and electronic fuel injection. A remap can adjust boost pressure, injection quantity and timing. The result is often a clear gain in torque, which makes the car feel stronger at low and medium revs, useful for overtaking and for towing. Parts to be careful with Dual mass flywheel and clutch: more torque puts extra load on them. Worn parts can fail quickly after a remap. Turbocharger: pushi...

Key takeaways Chiptuning changes the engine software to get more performance without changing hardware. Results vary by car, engine and tuner, so expectations should be realistic. Know the costs, risks, warranty and legal points before you start. Choose a reputable workshop and keep the original software saved.  Chiptuning is one of the most popular ways to get more performance from a car without changing the engine. Here is a simple guide to what it really involves. What is chiptuning? Every modern car has an engine control unit (ECU), a small computer that controls fuel, air, ignition timing and, in turbo engines, boost pressure. Chiptuning, today more often called an ECU remap, means changing the software settings in that computer so the engine delivers more power or torque. The name comes from older cars, where a physical chip was swapped. Today the software is usually rewritten through the car’s diagnostic port. How does it work? Manufacturers set conservative values so on...
