MMT V-TECH rolling road
Developed. Tested. Refined.
Our tuning software is developed in-house on our rolling road. Every vehicle is different, which is why we believe in measuring real-world results, refining performance and showing you exactly what your remap delivers.
- 01Baseline runBefore tuning begins, we carry out a baseline power run to measure your vehicle’s existing performance and check its suitability for tuning.
- 02Tailored tuningWe refine the software to suit your vehicle, using rolling road results to help achieve the right balance of power, torque, drivability and reliability.
- 03Before and after testingYour vehicle is tested again on the same rolling road, allowing you to compare its measured performance before and after tuning.
- 04Your results, in black and whiteYou’ll receive a printed dyno sheet showing your before-and-after power and torque figures, so you can see the results for yourself.
Curve shape indicative, drawn from the published peak figures. Your own printout comes off our rolling road, before and after.
Stages
Stage 1, 2 or 3?
The right stage depends on your car and any upgrades it already has. Tell us what’s been done or bring it in and we’ll take a look. Our health check is free, and we never tune a car that has a fault.

Came across MMT first time at Oulton Park, they have mapped a stage 1 tune on my Mini JCW, the car has been great since! Spoke to Clive and other people from MMT there and they were all super friendly and approachable, would recommend MMT to anyone that values great customer service and values their car.

Very nice and knowledgeable people. Had my Fiesta ST mapped by MMT and it was exactly what I wanted. Power increased very nice and smoothly with a lot of torque increase as well. They were very patient with my questions as well. Would recommend to anyone.

FAQs.
Is a remap safe for my engine?
Yes. When a remap is written specifically for your car and the engine is in good health, it stays well within the limits the parts were designed for. That’s why we start with a free health check, and why all our software is developed and either road-tested or tested on our rolling road. If we find a fault, we’ll fix it first. We never tune a car until it’s healthy.
Will it affect my insurance or warranty?
Yes. Tell your insurer. A remap is a modification, and most insurers cover it once it’s declared. If your car is still under warranty, the manufacturer could refuse claims on related parts, so speak to us before booking.
Can it go back to standard?
Yes. Before we make any changes, we read and securely save the car’s original factory file. If you ever want or need to return it to standard, we can simply write the original file back on to the car.
How long does it take?
Most Stage 1 remaps are done on the same day. Dyno sessions, gearbox tuning and Stage 2 or 3 tuning take a little longer; we’ll give you a time estimate when you book.
Do you remap at shows and events?
Yes! We attend a range of car shows and events throughout the year, and you can see where we’ll be on our social media pages or our events calendar. Spaces can be limited, so please get in touch beforehand to check we can support your vehicle and book your slot.
Can I pay monthly?
Yes. We offer flexible finance options, so you can spread the cost into manageable monthly payments. Just let us know when you book and we can discuss your options. Subject to status.
