Looking for petrol remapping in Birmingham? You’re in the right place.
At Remaps Birmingham, we help petrol car owners unlock serious performance gains with safe, custom ECU remapping. Whether you’re after sharper throttle response, more power, or just a more exciting drive — petrol remapping could be the game-changer your car needs.
This guide explains exactly how petrol remapping works, what kind of results you can expect, and what sets Remaps Birmingham apart.
What Is Petrol Remapping?
Petrol remapping is the process of adjusting your car’s ECU (Engine Control Unit) software to improve performance. The ECU controls how your engine behaves — including ignition timing, air/fuel ratios, throttle input, and boost pressure (if turbocharged).
Manufacturers intentionally restrict performance to suit global markets, meet emissions targets, and ensure reliability in all conditions.
By fine-tuning your petrol engine’s map, we unlock that hidden potential — safely and efficiently — for UK driving conditions.
Do Petrol Cars Benefit from Remapping?
Absolutely — especially if your petrol car is turbocharged or supercharged.
Modern petrol engines respond extremely well to tuning, often gaining significant horsepower and torque. Even naturally aspirated petrol engines can see improved throttle response and mid-range performance.
Here’s what a proper petrol remap can do for your vehicle:
More Power and Torque
Feel your car pull harder across the rev range. A remap can add 10–30% more power depending on the setup.
Sharper Throttle Response
No more delayed acceleration. A remap removes throttle lag, making your car feel quicker and more connected to your foot.
Higher Rev Limits (Where Safe)
We can safely raise rev limits to allow for a broader power band — ideal for performance driving and track use.
More Fun Behind the Wheel
Whether you’re overtaking, accelerating onto a dual carriageway, or cruising country roads — a remapped petrol car just feels more alive.
What Types of Petrol Cars Can Be Remapped?
We’ve tuned hundreds of petrol vehicles at Remaps Birmingham, including:
- Hot hatches (Golf GTI, Focus ST, Mini Cooper S)
- Coupes and saloons (BMW 320i, Audi A4 TFSI, Mercedes C200)
- Sports cars (Toyota GT86, Mazda MX-5, Porsche Cayman)
- Turbocharged hatchbacks and estates
- Naturally aspirated engines (with moderate gains)
If your petrol car has a turbo, the gains are usually bigger — but even non-turbo engines benefit from a custom tune.
How Much Does Petrol Remapping Cost?
Our pricing is simple, clear, and based on the stage of tuning your car requires:
Stage 1 – £260
Perfect for stock petrol vehicles. Delivers noticeable power gains and improved drivability without the need for physical mods.
Stage 2 – £350
For cars with bolt-on upgrades (performance intake, exhaust, intercooler). The map is tailored to make the most of your existing mods.
Stage 3 – £450
Full custom tuning for heavily modified or track-prepared vehicles. Ideal for upgraded turbos, injectors, or forged internals.
All prices include:
- Full diagnostics
- ECU backup
- Custom tuning (not a generic file)
- Post-remap testing and verification
- Lifetime support and rollback option
We don’t cut corners. Every petrol remap we do is bespoke and safe for daily use.
How Long Does It Take?
A petrol remap usually takes 1.5 to 3 hours depending on your vehicle and ECU type.
The process includes:
- Pre-remap diagnostic check
- Safe read of your ECU data
- Custom tuning based on your setup
- Upload of new software
- Final testing and road performance check
You can wait in our Birmingham workshop or drop your car off and collect it later in the day. We also offer mobile tuning in some cases — just ask when you book.
What Gains Can You Expect?
Every petrol engine is different, but here are some real examples from our workshop:
Ford Fiesta ST 1.6 EcoBoost (182bhp)
After Stage 1 remap: ~220bhp / 320Nm
Results: quicker throttle, stronger mid-range, more enjoyable drive
BMW 120i (non-turbo, 150bhp)
After Stage 1 remap: ~165bhp
Results: smoother throttle response, improved pickup, better low-end torque
Audi A3 2.0 TFSI (200bhp)
After Stage 1 remap: ~245bhp / 400Nm
Results: more urgent acceleration, perfect for motorway driving
We always give realistic, vehicle-specific estimates before we start. No exaggerated claims.
Is It Safe to Remap a Petrol Engine?
Yes — as long as it’s done by professionals.
At Remaps Birmingham, we tune well within the safe mechanical limits of your engine, turbo, clutch, and gearbox.
We never chase big dyno numbers just for the sake of it. Our remaps are designed for real-world performance, reliability, and longevity.
Before tuning, we run a full diagnostic scan. If something doesn’t look right, we won’t proceed — and we’ll explain why.
Will a Remap Affect Fuel Economy?
It depends on how you drive.
If you push your car harder after a remap (which most drivers do), you may use a little more fuel.
However, if you drive sensibly, you might actually see a small improvement in MPG, especially during cruising. That’s because your engine runs more efficiently post-remap.
The focus with petrol remapping is usually on performance gains, but economy improvements are a nice bonus for some drivers.
What About Insurance and Warranty?
Insurance
Yes, you should declare the remap to your insurer. Some may increase your premium slightly, others may not mind.
We provide full documentation to help you stay compliant. Not declaring it could invalidate your policy.
Warranty
If your car is under manufacturer warranty, a remap could affect it — especially for the engine and drivetrain.
Some ECUs show a “flash counter” that dealers can detect. Others do not. Speak to us if warranty is a concern — we’ll explain your options clearly.
Can I Go Back to the Factory Settings?
Yes. Before we remap your petrol car, we save a full backup of the original ECU software.
If you ever want to go back to factory settings (e.g. before selling the car), we’ll restore the original map free of charge.
