Increase the power and performance of your BMW with our custom BMW remap services. We are a team of expert BMW tuners dedicated to improving your cars performance.
Find Your BMW Model
The first step in tuning a BMW is to know its exact specifications. You can find your car’s original Brake Horsepower (BHP) and torque figures by utilising an online car checking tool. This gives us a baseline for our work. For a precise reading, our expert technicians can assess your engine’s current output on our workshop dynamometer.

The Benefits of Tuning Your BMW Vehicle
A custom BMW remap from VIEZU transforms how your car feels to drive. We tailor every tune to your specific priorities, focusing on making your BMW more responsive, powerful and enjoyable in a way you can feel every time you get behind the wheel.
Whether you want maximum performance, improved fuel economy or a perfect balance of both, we have a solution for you.
Enhanced Performance and Driveability
For drivers seeking maximum thrills, our performance remaps deliver significant power and torque gains across the entire rev range. We target and reduce common issues like turbo lag and flat spots in the power curve, resulting in stronger, more immediate acceleration. This improved power delivery, combined with a sharper throttle response, gives you precise control and a truly dynamic driving experience.
Blended Tuning: Power and Economy Combined
Our most popular option offers the best of both worlds. A blended tune provides thrilling performance gains and improved throttle response similar to a performance map, while also incorporating the smart fuel-saving strategies of an economy tune for when you’re driving normally. By carefully adjusting the engine’s air-fuel ratio and ignition timing for light-load conditions, like cruising on a motorway, you can enjoy a significant power boost without sacrificing fuel efficiency on your daily commute.
Dedicated
Economy Tuning
If maximum fuel efficiency is your number one priority, our dedicated economy tunes are the perfect choice. This service is specifically designed to make your engine run as efficiently as possible in normal driving, delivering the best possible improvement in MPG and saving you money at the pump.
Proven Performance: Dyno-Developed & Verified
We provide proven measurable results. Our in-house 3000bhp 4-wheel drive dynamometer is central to our research and development where our tuning is tested and checked. This ensures you know exactly what gains to expect from your BMW remapping. For instance a professional tune on a BMW M140i can take the standard 340hp to over 420hp.
Case Study: The HALO BMW M3 'Gravity Wave' Project
For a complete picture of what’s possible look no further than our Halo Project: the BMW M3 ‘Gravity Wave’. This project was more than a simple remap; it was a complete vehicle transformation created through a partnership between VIEZU’s software expertise and Paramount Performance’s mechanical engineering. The performance upgrade combines a highly advanced Burger Motorsport JB4 tuning system with a high-flow custom cold air intake and a stainless steel sports exhaust. To match the power the ‘Gravity Wave’ package includes a full suite of lightweight dry carbon fibre styling.
The result is a dyno-verified leap in performance and a look that really turns heads.
- Factory Power: 510 HP / 650 NM
- After VIEZU Tune & Upgrades: 631 BHP / 810 NM
Stage 1, Stage 2 & Stage 3 BMW Tuning
We offer staged tuning packages to match your car and performance goals:
Stage 1 BMW Remap
A software upgrade for a standard vehicle. This vehicle remap optimises your engine’s settings to improve power, torque, and throttle response without needing new parts and mechanical upgrades.
Stage 2 Remap
For cars with existing mechanical upgrades. A Stage 2 BMW remap is combined with mechanical parts like a performance air intake, and a sports exhaust. The tailored remap ensures you get the most out of your mechanical upgrades.
BMW Stage 3 Tuning
This is our most advanced custom tuning for highly modified cars. Stage 3 tuning is utilised with vehicles that have had major mechanical upgrades like larger turbos. Each Stage 3 tune is developed on our dyno to ensure all parts work together for maximum, reliable power.
BMW Petrol Tuning
VIEZU has years of experience remapping petrol BMW engines. We write custom software designed to optimise your engine’s performance. We consider your vehicle’s model, engine type and any existing modifications. Our team at our workshop in Warwickshire can provide expert advice and recommendations.
BMW 3 Series F34 2.0 Petrol Example
- Original BHP 184
- Power + (Perf) BHP 66
- Original Torque 290
- Torque + (Perf) Nm 150
BMW Diesel Tuning
Our BMW diesel tuning services give you the same benefits as our petrol remapping. We create a custom solution that improves both performance and efficiency. Our tuning team knows how to maximise the potential of diesel BMW engines, from a BMW 118d remap to a BMW 640d remap. We deliver a complete solution that enhances performance and prioritises the long life and safety of your engine.
BMW 3 Series F34 2.0 Diesel Example
- Original BHP 150
- Power + (Perf) BHP 40
- Original Torque 320
- Torque + (Perf) Nm 80
BMW Gearbox Tuning (TCU Remapping)
An engine tune is only half the story. Our TCU (Transmission Control Unit) tuning, also known as gearbox tuning, is designed to work with our engine remaps. By recalibrating the gearbox software, we increase clutch pressure to handle more torque and improve shift response by up to 20%. This provides a much more responsive and engaging drive.
Performance Parts & Mechanical Upgrades
To get Stage 2 and Stage 3 power, mechanical upgrades are needed. We supply and install proven performance parts including exhausts, air intakes, intercoolers, big brake kits and suspension upgrades. Whether you need BMW M2 tuning parts or a simple panel filter, we can help.
Our BMW Tuning Process
Our tuning process begins with a full vehicle health check and diagnostic scan. We then run your car on our dynamometer to measure its standard performance. Our technical team read the original ECU file and write a new calibration based on your car and requirements. The new software is uploaded and we run the car on the dyno again to verify the performance gains. We finish with road tests to ensure perfect driveability.
Why Choose VIEZU as your BMW Remap Specialist?
As a leading BMW tuning specialist we know your car stands for performance and precision. Unlike some BMW tuning companies we write every single tuning file ourselves. Each BMW tune is developed in-house by our skilled team to meet your specific needs. We test our BMW remaps on our rolling road at our workshop ensuring reliable performance. With our workshop centrally located and a UK-wide network our fully insured service provides complete peace of mind backed by a money-back guarantee.

~ Neil Windsor (Google Verified Review)
“What a great bunch of people! And they are not only helpful but the results are awesome, and they REALLY know their stuff! Had our BMW remapped recently, the car drives so much better, the performance was increased by almost 90 Bhp. The most important thing is the way the car drives, and it’s like a different car! The service is fantastic, and once your car is remapped, you’ll feel the difference! VIEZU also offer a 30 day money back guarantee – so you can have true confidence in them! If you’re looking for a little more power or economy (or even a blend of the two), then VIEZU is the place to trust with your pride and joy!
BMW Tuning Frequently Asked Questions
How much does it cost to remap a BMW?
The cost to remap a BMW varies based on the vehicle’s age model and ECU type. For instance a newer BMW with a complex encrypted ECU will require more development time than an older model. Any hardware upgrades you choose would also affect the price. For a precise quote tailored to your vehicle and needs contact us today on +44 (0)1789 774444, email info@viezu.com or use our online chat.
What is the difference between a remap and a BMW tuning box?
A remap directly changes the software on the car’s ECU for a fully integrated tune. A BMW tuning box is a plug-in device that intercepts signals to the engine which is a less sophisticated method. For a complete and customisable upgrade remapping is the popular choice.
Can you tune a diesel BMW?
Yes we are experts in BMW diesel tuning. Our team has the knowledge and experience to get the best from the performance of all diesel BMWs.
How do you ensure engine safety and reliability with increased power?
Engine safety is the most important part of our work. We use a careful process that relies on real data from decades of experience. Before any changes are made your BMW undergoes a full diagnostic scan and vehicle health check. Our goal is to get the best performance within the safe mechanical limits of your vehicle’s engine turbo and transmission for long-term dependability.
