Three problem areas that cost diesel owners the most. We handle all three properly, with backup files saved for life and clear honest advice on what your vehicle actually needs.
The beautiful period town of Reigate, with its convenient access via the A217, is home to many discerning vehicle owners. From high performance sports cars to premium German saloons and SUVs, there is a clear appreciation for quality engineering.
Our custom ECU remaps are the perfect way to safely enhance the performance and driving characteristics of these vehicles.
Whether you're looking to improve the fuel economy of your diesel SUV for the school run or unlock the full performance potential of your weekend sports car, an ECU remap from VMAX is the answer. We tailor every map to the vehicle and the owner's requirements, ensuring a flawless result.
Our mobile service means maximum convenience for you.
01 · No hardware changes required
A Stage 1 remap is the perfect choice for a standard, unmodified vehicle. It is designed to deliver impressive power and torque gains purely through software adjustments.
No mechanical or hardware changes are necessary, making it a safe and cost effective upgrade. We optimise the engine's parameters to improve throttle response, widen the power band, and make the vehicle feel much more responsive.
You can typically expect a 20 to 30 percent increase in both power and torque on most turbocharged engines. This option is ideal for drivers seeking a better daily driving experience without compromising reliability.
02 · For modified vehicles
A Stage 2 remap is for enthusiasts who have already upgraded their vehicle's hardware. These modifications often include performance exhausts, upgraded intercoolers, or improved air intake systems.
A standard map cannot take full advantage of these changes. Our Stage 2 custom file is written specifically to work with your hardware modifications, ensuring they all function in harmony.
This allows for much larger power and torque gains than a Stage 1 tune, pushing your vehicle to its full performance potential. A Stage 2 remap requires a detailed assessment to create the perfect engine calibration for your specific setup.
03 · MPG-focused for fleet and daily use
Economy tuning is designed to save you money at the pumps by maximising your vehicle's fuel efficiency. It is the ideal solution for high mileage drivers, taxi operators, and commercial fleet managers.
By optimising the torque curve, we can make the engine operate more efficiently at lower RPMs. This means you need less throttle to maintain speed, resulting in significant MPG improvements.
While the focus is on fuel economy, many drivers also notice smoother power delivery and improved driveability. For fleet owners, even a small MPG increase per vehicle can add up to huge annual savings.
04 · At your home, workplace or yard
All our ECU tuning services are fully mobile. We understand that taking your vehicle to a workshop is not always convenient.
Our mobile ECU remap service brings our expertise and dealer grade equipment directly to you, anywhere in our Sussex and Surrey coverage area. We can perform the entire remapping process at your home, office, or commercial yard, at a time that suits your schedule.
This minimises downtime for your business and removes the hassle of travel. Our mobile tuning vans are equipped with everything needed to provide a safe, efficient, and professional car remapping service on site.
We are the local experts for DPF and EGR issues on premium diesel cars in Reigate. Our mobile service can resolve these common problems efficiently, restoring performance and reliability.

The most common things customers ask us before we visit.
Typical session is 90 minutes to 2 hours. Reading the factory file, writing a custom calibration, flashing it back, clearing codes and road test. No driving to a workshop, no courtesy car.
Any software modification can affect warranty if detected. We keep your original file on record so the vehicle can be reverted before a dealer visit. Talk to us about your specific warranty situation before booking.
Yes. Any vehicle modification including a remap must be declared. Most insurers handle this with a small admin change. A few specialist modified-car insurers are much cheaper than main stream providers for remapped vehicles.
Yes when done properly. We tune within safe factory tolerances, use custom files per engine code, and road test every vehicle before handover. Poorly written generic files are where problems start, which is why we do not use them.
Yes. We save your original factory file at the start of every job. If you ever need to return to stock, we flash the original file back in around 30 to 45 minutes. Useful for dealer servicing or resale.
Usually yes. Call or message with your registration and postcode and we confirm an exact slot, same day or next day.
