Vehicle Tuning Levels

Stage 1
A Stage 1 remap is the perfect entry point for upgrading performance without making physical changes to the engine. This software-based upgrade is developed in-house to increase power and efficiency while keeping factory safety parameters intact. You can expect better throttle response and improved drivability, with the potential for fuel economy gains on diesel vehicles where efficiency diesel tuning is applied (such as VIEZU’s BlueOptimize™ remap).
Ideal for everyday drivers who want more from their vehicle without affecting reliability or comfort.

Stage 2
A Stage 2 remap builds on the Stage 1 upgrade and works in harmony with hardware modifications such as a free-flowing exhaust, a smaller supercharger pulley or cold air intake.
This level of remapping adjusts the ECU to maximise performance from your mechanical upgrades. All tuning is carried out with care to retain safe operation and everyday usability, giving you sharper throttle response, more torque and stronger power delivery.
Designed for enthusiasts looking to get the most from their enhanced setup.

Stage 3
A Stage 3 remap is fully bespoke and suited to highly modified vehicles with components such as larger turbos, high-flow injectors, uprated fuel systems and other motorsport-grade hardware.
Tuning is carried out live on our 3,000hp rolling road with real-time data logging. Every parameter is adjusted by our expert calibrators to ensure maximum performance, response and control across the full rev range.
This service is tailored for serious drivers looking for uncompromising results from a fully customised calibration.

How much should a remap cost?
The cost of a remap can vary depending on the level of tuning and the specific requirements of your vehicle. At VIEZU, a Stage 1 remap, which is designed for standard vehicles without mechanical modifications, typically starts at £200 – £300 (vehicle dependant). This entry-level remap focuses on improving power, torque and, where appropriate, fuel economy, all while maintaining factory safety limits and reliability.
For drivers who have made mechanical upgrades such as performance exhausts or intakes, Stage 2 and Stage 3 remaps are available. These involve more complex calibration and may include live tuning on VIEZU’s 3,000hp rolling road. As a result, they come at a higher cost, with Stage 3 often reaching into the thousands depending on the extent of the modifications. Prices reflect the depth of customisation, testing and support provided by VIEZU’s in-house technical team.

Is remapping a car good for the engine?
Remapping a car is generally good for the engine when carried out by a reputable and professional tuning service like VIEZU. By optimising key parameters such as air-fuel ratios, ignition timing and boost pressure, a remap can improve throttle response, enhance power delivery and support more efficient combustion.
Is it better to chip or remap?
Chip tuning is an older, more invasive method suited only to pre-2000 vehicles with non-reprogrammable ECUs. Modern tuning tools and remapping are now the standard for nearly all performance, efficiency and drivability improvements allowing detailed adjustments to the engine’s software without modifying any hardware. For this reason for most vehicles, remapping is usually chosen and it is safer, more precise and fully reversible.
