Coventry Car Remapping
Contents
Paramount Performance is a specialist vehicle tuning centre providing professional engine remapping services to clients across Coventry and Warwickshire. Whether your daily drive takes you past the iconic Cathedral spires or out into the surrounding countryside, we replace standard manufacturer software with a custom-written calibration remap to improve your vehicle’s power, torque and throttle response. Our Coventry car remapping work is validated on our in-house 4×4 dynamometer, ensuring every tune delivers safe, quantifiable results.
The Importance of Verifiable, Dyno-Proven Results
Many Coventry car remapping companies offer a mobile service. This method involves tuning a vehicle on the road, which lacks the controlled environment needed to accurately measure engine output. A dynamometer or rolling road, is the only professional tool to quantify performance gains precisely. It establishes a baseline of your car’s power and provides a printed graph showing the exact improvements after tuning. Our Coventry car remapping process is built on providing measurable proof, ensuring the results are real, safe and tailored to your vehicle.
Our Custom ECU Remapping Services in Coventry
We offer several vehicle tuning services designed to meet specific objectives, from outright performance to improved fuel efficiency. All our tuning files are custom-written in-house by our technical team.
Stage 1 Remap
A Stage 1 remap is designed for a vehicle with standard factory hardware. The software is expertly calibrated to optimise performance within the safe operational limits of the original components. This offers an excellent balance of increased power, improved driveability and long-term engine reliability.
Stage 2 Remap
A Stage 2 remap is for drivers seeking further performance and requires supporting hardware modifications. This typically includes upgrades to the exhaust system, air intake or intercooler. The ECU is then recalibrated to leverage these hardware enhancements for more significant power and torque gains. We can also supply and fit a wide range of car performance parts to complete your Stage 2 package.
Economy Tuning
Our economy tuning is focused on improving fuel efficiency. By increasing torque in the lower rev range, the engine operates under less strain, often resulting in improved MPG and a smoother power delivery. This is a popular option for diesel and commercial vehicles.




The Paramount Performance Coventry Car Remapping Process
Our tuning process has been refined over three decades to ensure safety, quality and consistent results. This is the standard procedure at our workshop:
- Initial Consultation & Vehicle Health Check: We discuss your requirements and perform a thorough diagnostic health check to confirm your vehicle is in suitable condition for tuning.
- Baseline Dyno Run: We measure the vehicle’s stock power and torque on our 4×4 rolling road to establish a performance baseline.
- ECU Data Reading: Our technicians read the original software map from your vehicle’s Engine Control Unit (ECU) using professional, licensed tools.
- Custom File Writing: Our file writers meticulously adjust the software parameters based on the vehicle data and your requirements. We do not use generic files.
- Uploading the New Software: The newly optimised software file is carefully written to the ECU.
Final Dyno Run & Verification: A final dyno run measures the new power and torque figures. You receive a printout showing the precise, proven gains.

Coventry Car Remapping Frequently Asked Questions
Is ECU remapping safe for my engine?
Yes, Coventry car remapping when performed by qualified experts using authentic equipment. We tune vehicles well within the safe operating limits of engine and drivetrain components. Our custom, data-led approach is considerably safer than using cheap, generic files that can push components beyond their tolerance levels. There are so many benefits of ECU remapping that you can read here.
How much power will my car gain?
The potential gains are specific to the make, model, and engine type of your vehicle. Please contact us with your vehicle details for an accurate estimate of the expected performance increases.
Will a remap affect fuel economy?
In many cases, fuel economy improves after remapping. By optimising the engine’s torque delivery, it operates more efficiently. For like-for-like driving, many customers, especially with diesel engines report a noticeable improvement in MPG.
How long does the remapping process take?

Customer Testimonials
”Had my XFR remapped and put on the dyno today. From the first email enquiry to having the car in the workshop Tom and viezu/paramount a have been fantastic. Definitely the go to for Jaguar owners.
~ Daniel Tongue (Verified Google Review)
”Booked in for a remap of my Jaguar F-Type, to unleash the shackles of the 450hp map it came with from the factory (though this turned out to actually be 500hp). A couple of hours, and a mug of coffee later, the car was equipped with over 620 galloping horses and enough torque to spin the Earth off its normal axis. The remap has transformed the car’s performance would be a huge understatement. It was never that slow before, but it is now a fully uncaged jaguar, roaring to all those cars following with a growl that causes sensitive souls to cower behind their seats like a 10-year old watching Doctor Who in the 70s.
From the people, the service and the work they carried out, I cannot recommend the team at Paramount Performance highly enough.
