Our Tuning Partner
We work exclusively with JF Automotive — industry leaders with over 13 years of experience and more than 25,000 vehicles tuned. Their in-house software engineers develop custom dyno-calibrated files focused on safe, usable, real-world performance.
Why Remap Your Vehicle?
Manufacturers calibrate vehicles conservatively to suit global climates, fuel qualities and emissions targets. A professional remap safely optimises those parameters to improve drivability and performance.
- Stronger in-gear acceleration
- Improved throttle response
- Smoother torque delivery
- Optional gearbox optimisation

Remapping FAQs
What warranty do you offer?
We do not offer a separate warranty on performance software. As with all tuning providers, modifications increase mechanical stress and therefore cannot be covered under a traditional warranty structure.
We are always transparent about this. Please refer to our Terms & Conditions for full details before booking.
Will you carry out a health check on my vehicle?
We do not carry out mechanical strip-down inspections. It is the owner’s responsibility to ensure the vehicle is in good mechanical condition prior to tuning.
If a vehicle presents with warning lights, faults, smoke, abnormal noises, or known issues, we reserve the right to refuse tuning.
Why have I not received a reply to my quote?
The most common reasons are:
- An incorrect email address was entered
- The reply has gone to your spam/junk folder
- The enquiry relates to a vehicle we do not support
All genuine enquiries are responded to. If you have not heard back, please check your spam folder before contacting us again.
I have tried calling but the phone does not ring
Our phone lines operate Monday–Friday, 10am–4pm. If you are calling outside of these hours, the phone will not ring.
If you call during opening hours and we are unable to answer, we are likely working in the workshop. Please leave a message or send an email.
I am outside your unit — why are you closed?
We operate strictly by appointment only. We are not a walk-in retail premises.
If you do not have a confirmed booking, the workshop may be closed to the public while work is carried out.
Can I enter the workshop or stay in the vehicle while work is carried out?
No. For safety and insurance reasons, customers are not permitted in the workshop or inside the vehicle during the tuning process.
The workshop environment contains moving vehicles, electrical equipment and lifting systems, and must remain distraction-free.
How can I pay?
We accept cash or card payments on the day.
If paying by bank transfer (BACS), funds must be cleared at least 2 hours prior to arrival.
How long does the process take?
Please allow up to 2 hours for a typical remap appointment. Some vehicles may require additional time depending on complexity, read/write speeds, or software revisions.
How do I book?
You can book via:
- The contact form on our website
- The gains calculator tool
- Direct message via Facebook or Instagram
- Phone during business hours
What dates do you have available?
Please provide your preferred date when enquiring. We will then confirm availability for that specific date.
Do you offer finance?
Yes. We offer 0% interest finance over 3 months via Payment Assist.
Finance must be arranged and approved prior to your booking date.
If you close at 4pm, can I book in for 4pm?
No. 4pm is our closing time.
The last booking slot is typically between 2–3pm depending on the vehicle and work required.
Is remapping safe for my vehicle?
A remap is safe when carried out on a mechanically healthy vehicle using professionally developed software.
However, tuning will not repair or mask existing mechanical faults. It is the owner’s responsibility to ensure the vehicle is properly maintained prior to modification.
I have sent a message but not received a reply
Please allow up to 2 working days for a response. We respond to enquiries in the order they are received.
What happens if I arrive late?
If you arrive significantly late, we may not be able to proceed with the booking due to other scheduled work.
Missed appointments or no-shows may result in loss of deposit.
