Looking for custom remaps in Birmingham? You’ve come to the right place.
At Remaps Birmingham, we specialise in bespoke ECU tuning designed around your car, your modifications, and your driving style. No off-the-shelf files. No copy-paste maps. Just custom performance tuning — built from the ground up to give you the best results possible.
Whether you drive a daily diesel, a turbocharged petrol, a heavily modified track car, or a van loaded with tools, this guide explains exactly what a custom remap is, how it works, and why it’s worth every penny.
What Is a Custom Remap?
A custom remap is a personalised ECU tune created specifically for your vehicle. It adjusts the core engine settings — like fuel delivery, turbo boost, torque limits, and throttle response — to extract the most from your setup.
Unlike generic tuning files that use a one-size-fits-all approach, a custom remap is crafted using:
- Your vehicle’s current hardware and software
- Any performance modifications you’ve added
- Real-time data logging during testing
- Your personal driving preferences (e.g. economy, responsiveness, max power)
It’s not just about more power — it’s about the right power, delivered the right way, for your car.
Who Is Custom Remapping For?
Custom remaps are ideal if:
- You’ve already modified your car (intake, exhaust, intercooler, turbo, etc.)
- You want more than what a standard Stage 1 map offers
- You have a unique driving setup — like towing, track use, or off-roading
- You want the safest and most optimised tune possible
- You simply want the best out of your engine
Many of our clients at Remaps Birmingham choose a custom remap after upgrading their car or feeling underwhelmed by a previous tune from another tuner.
What Are the Benefits of a Custom Remap?
The gains with a custom remap go beyond just numbers on paper. Here’s what you can expect:
Maximum Safe Performance
Because the map is built around your specific car, we can safely push performance further than a generic file — without compromising reliability.
Perfect Match for Your Modifications
A custom remap lets us take full advantage of any upgrades you’ve made. That includes:
- Sports exhaust systems
- Induction kits
- Uprated intercoolers
- Hybrid or larger turbos
- Fuel system upgrades
You’ll get the full value out of every mod you’ve paid for.
Improved Throttle and Boost Control
Fine-tuned throttle mapping makes your car feel sharper and more responsive — ideal for spirited driving or track use.
Boost pressure can be adjusted for smoother delivery or a more aggressive surge, depending on your preference.
Enhanced Driveability
One of the biggest benefits of a custom remap is how drivable the car becomes. Smoother power curves, refined low-end torque, and better gear-to-gear transitions all make daily driving easier and more enjoyable.
Customised for How You Drive
You tell us what matters most — power, economy, towing support, or even track performance — and we build the map to deliver exactly that.
What Does a Custom Remap Involve?
At Remaps Birmingham, our custom remap service includes:
- Pre-tune diagnostics – to check for existing faults or mechanical issues
- Data logging and ECU read – safely extract your current software
- Map building – we modify fuel, ignition, boost, and torque settings
- Upload and testing – the custom map is installed and tested
- Live road data collection – fine-tune the map using real-world driving
- Final diagnostics and backup – confirm performance and store your original file
This is not a quick “flash-and-go” job. It’s a detailed, methodical process that prioritises results, safety, and long-term performance.
How Long Does a Custom Remap Take?
A custom remap usually takes 3 to 5 hours depending on the vehicle, modifications, and tuning goals.
Some highly modified cars may take longer due to the level of testing and adjustments needed.
We’ll always give you an estimated time in advance — and keep you updated throughout the process.
How Much Does a Custom Remap Cost?
Our custom tuning packages are priced based on the stage of tune:
- Stage 1 (stock engine): £260
- Stage 2 (with bolt-on mods): £350
- Stage 3 (heavily modified setups): £450
These are fixed, all-inclusive prices. No hidden extras. No surprise charges.
Custom remaps always include:
- Full diagnostics
- ECU backup
- Data logging
- Custom tuning
- Road testing
- Ongoing support
If you’ve got a complex setup, we’ll walk you through the process and give you honest advice on what’s achievable.
What Kind of Gains Can I Expect?
Here are a few real examples from our customers in Birmingham:
VW Golf GTI (Stage 2 with intake and exhaust)
From 230bhp → ~290bhp / 420Nm
Sharper throttle, no turbo lag, smoother boost curve
Audi A4 2.0 TDI (stock)
From 140bhp → ~185bhp / 400Nm
More low-end torque, better MPG, smoother gear transitions
Ford Fiesta ST (Stage 3 with hybrid turbo)
From 200bhp → ~280+bhp / 470Nm
Aggressive mid-range pull, custom launch control, optimised for track use
Each car is different. We never promise unrealistic numbers — but we always deliver a measurable improvement.
Will It Affect Reliability?
No — as long as the map is done properly.
Our custom remaps are built within the safe operating limits of your engine, gearbox, turbo, clutch, and cooling system. We don’t push beyond what your setup can handle.
We also perform pre- and post-tune diagnostics to make sure your car is running safely at all times.
Can You Revert Back to Stock?
Yes. We back up your original ECU file before we start.
If you ever want to remove your remap — for example, when selling the car — we’ll reinstall the original software free of charge.
Will It Affect My MOT or Insurance?
MOT
As long as we don’t modify or delete emissions systems (like the DPF or EGR), your remap will not affect your MOT. All of our road-going remaps are MOT-compliant.
Insurance
You should declare your custom remap to your insurer. Some will adjust your premium, others may not. We provide tuning documentation to help you stay compliant.
