Yes, we often have same-week appointments available, and sometimes same-day service depending on our schedule. Our mobile service makes it easy to fit around your schedule - we can come to your home or workplace at a time that suits you.
To provide an accurate quote, we need your vehicle's make, model, year, engine size, and fuel type. It's also helpful to know what type of service you're interested in (ECU remap, performance tuning, economy mapping, etc.) and what your goals are (more power, better fuel economy, etc.).
We're open Monday to Friday from 8:00 AM to 6:00 PM, Saturday from 8:00 AM to 4:00 PM, and Sunday from 8:00 AM to 2:00 PM. We're flexible with our mobile service and can often accommodate appointments outside these hours by arrangement. Contact us to discuss your preferred timing.

This service is extremely popular as it saves you time and allows you to continue with your day.
Our workshop is fully mobile, with no specific location. We serve the wider Midlands area including Rugby, Coventry, Leicester, Lutterworth, Northampton, Kettering, Hinckley, Nuneaton, Leamington Spa, Warwick, and everywhere in between. We can come to you with our mobile service.
While we don't currently have an online booking system, booking is quick and easy. Simply call us on 07773 694570, send us a WhatsApp message, or use the contact form on this page. We'll respond promptly and arrange a convenient time for your service. Most inquiries are handled within a few hours.
Yes, absolutely! If you have your vehicle details handy (make, model, year, engine size, fuel type), we can often provide an accurate quote immediately over the phone. For more complex requirements or modified vehicles, we may need to see the car first, but we'll give you a ballpark figure during the call.
We accept multiple payment methods for your convenience including cash, bank transfer, and all major debit/credit cards. Payment is taken after the work is completed and you're fully satisfied with the results. We can also discuss payment plans for larger jobs if needed.
Yes, you're more than welcome to watch the remapping process if you visit our workshop. Many customers find it fascinating to see how ECU remapping works. We're happy to explain each step of the process and answer any questions you have. If we're providing mobile service at your location, you can observe the entire process there too.
Our primary service area covers the Midlands region within a 20-25 mile radius of Rugby/Lutterworth for mobile service. However, if you're outside this area, you're welcome to visit our Lutterworth workshop, and we serve customers from across the UK who travel to us. For customers further afield with multiple vehicles or fleet requirements, we may be able to arrange special visits – contact us to discuss your needs.
Customer satisfaction is our absolute priority. We offer a comprehensive 30-day satisfaction guarantee on all our work. If you're not completely happy with the results, we'll work with you to adjust the mapping, or if you're still not satisfied, we'll provide a full refund and restore your original ECU file, no questions asked. We also keep your original file backed up indefinitely for your peace of mind.
