Frequently Asked
Questions

Everything you need to know about our tuning services, the process and what to expect on the day.

Safety & Tuning
Is it safe to remap or tune an engine? +

Yes. The way we tune every vehicle is safe. Before any tuning takes place, we carry out a full health check to ensure the vehicle is running correctly and is fit for tuning. We also ensure all tuning stays within the safe operating limits of the engine and its components.

We never push a vehicle beyond what it can safely handle. If we identify any issues during the health check, we will advise you before proceeding.

Is it safe to dyno a vehicle? +

Dyno tuning is a safe and controlled way to tune a vehicle's engine management system. Your vehicle is securely strapped to the rolling road, which simulates real road conditions and allows for accurate measurements of power output.

Our technician can make adjustments to the engine management system in real time, ensuring the vehicle remains within safe operating parameters throughout the entire process. Data logging during the session allows us to monitor performance at every stage and make further adjustments if needed.

All xDrive and 4WD vehicles are tuned on our mechanically linked V-Tech 4WD dyno, which is fully xDrive safe. Unlike non-linked dynos, ours eliminates the risk of driveline stress or transfer box damage.

Can remapping or tuning void my warranty? +

It is possible that remapping or tuning could affect your manufacturer warranty. Some manufacturers consider ECU modifications to be an unauthorised change and may not cover repairs or issues that arise as a result.

We always recommend checking the terms and conditions of your warranty and speaking with your manufacturer or dealership before booking. Our team is happy to advise you on this if you have any questions.

The Process
Is all tuning done on a dyno? +

Yes. All of our tuning is carried out on our dyno rolling road. This allows us to accurately measure power output and torque before and after tuning, and make any necessary software adjustments in a safe, controlled environment.

Data logging during the session ensures we create the best possible result for your specific vehicle. You also receive a full before and after power printout so you can see exactly what your vehicle is producing at every point across the rev range.

How long does Stage 1 tuning take? Can I wait on site? +

Stage 1 dyno tuning typically takes 2 to 4 hours to complete, depending on the vehicle and any additional services booked alongside it.

You are more than welcome to wait on site. We have a warm, comfortable waiting area with free Wi-Fi, free drinks and Netflix to keep you comfortable throughout your appointment.

Do I get a printout showing before and after performance? +

Yes. You will receive a full printout showing the before and after performance of your vehicle. This includes power output, engine bhp, and torque figures, allowing you to see exactly what improvements the tuning has made.

It's something we are proud to hand over — there is nothing to hide when you tune on a dyno.

Can I just turn up, or do I need to book? +

We operate by appointment only. Walk-ins cannot be accommodated as each session requires dedicated dyno time and preparation.

Booking is quick and easy — you can secure your slot via our website using the link below.

Our Service
What is the difference between DC Remapping and a mobile flash or cheaper map with no dyno? +

The difference is significant. Our custom Stage 1 dyno tuning involves fine-tuning the engine management system on a rolling road, which allows us to accurately measure and adjust engine parameters including power output, torque, air-fuel ratio and boost pressure in real time.

This ensures the engine is operating within safe limits and that the calibration is fully optimised for your specific vehicle and its components. Mobile flash maps or cheaper off-the-shelf maps written without a dyno cannot offer this level of precision. They do not account for the unique characteristics of your vehicle and are written blind.

Every tune we write is developed in-house, on the dyno, in front of us. No generic files. No guesswork. You also receive a detailed before and after dyno printout at the end of every session.

Is it just dyno tuning you offer? +

Our primary speciality is custom dyno tuning, where we adjust the ECU programming to optimise engine performance and power output. However, we also offer a range of additional services including:

Gearbox tuning (xHP)  ·  DPF delete  ·  EGR delete  ·  AdBlue delete

If you are unsure what is right for your vehicle, get in touch and we will advise you on the best approach.
