Stage 3 Remaps in Birmingham: Tuned For Increased Performance

You’re not here for a small upgrade. You’ve done Stage 1. You’ve probably done Stage 2. Now you’re chasing serious power.

Stage 3 remaps are for drivers who’ve invested in major hardware upgrades and want to push their car to its full potential. If you’re based in Birmingham and want a truly custom tune that matches your high-performance build, you’re in the right place.

At Remaps Birmingham, we work with modified vehicles every week. From bigger turbos to uprated fuel systems, we tune cars with real power and real precision. This guide will walk you through everything you need to know about Stage 3 ECU remapping — and why it’s not for the faint-hearted.

What Is a Stage 3 Remap?

A Stage 3 remap is a fully bespoke engine tune designed for vehicles with major aftermarket modifications. This usually includes:

• Larger turbo or supercharger
• Upgraded injectors and fuel pump
• High-flow intake and exhaust systems
• Bigger intercoolers
• Strengthened clutch or gearbox (manual or DSG)
• Forged internals (in some cases)

With these mods installed, your ECU needs to be recalibrated from the ground up. This isn’t just about turning up the boost — it’s about rebalancing fuel, timing, airflow, and torque control systems for a custom build.

What Kind of Power Can You Expect?

There’s no single answer to this — Stage 3 is completely dependent on your hardware setup.

We’ve tuned Stage 3 builds that make:

• 500+ bhp in turbocharged petrol cars
• 800+ Nm of torque in diesel setups
• Quarter-mile times in the low 12s (or less)

If you’ve built your car for performance, Stage 3 is how you make it work together. It’s the final piece of the puzzle.

Example: Audi S3 with Hybrid Turbo

With a hybrid turbo, high-pressure fuel pump, full intake and exhaust upgrades, and intercooler — we’ve tuned local S3s to push beyond 450 bhp while retaining excellent street manners.

The goal with Stage 3 is always usable power, not just dyno glory.

What Does a Stage 3 Remap Cost?

Stage 3 tuning at Remaps Birmingham starts from 450.

Because every car is different, we quote on a case-by-case basis. Stage 3 maps are fully custom-built and require more time, data logging, and test runs than lower stages.

You’re not just paying for a remap. You’re investing in proper calibration for your high-performance build.

What’s Included?

Our Stage 3 remap package includes:

• Full vehicle health check
• Scan for fault codes and baseline logging
• Backup of original ECU map
• Custom tuning tailored to your exact mods
• Test drives and fine-tuning
• Post-map checks and support

We may also recommend additional upgrades based on our assessment — we’re not here to just flash the ECU and send you off. We want your car to run safely, reliably, and as fast as it should.

Is Stage 3 Right for You?

Stage 3 is not for everyone. It’s best suited to drivers who:

• Have invested in significant hardware upgrades
• Want to run high boost or fuel flow safely
• Accept that reliability depends on the quality of the build
• Are happy to run premium fuel (or even race blends)
• Are okay with higher maintenance needs

If that sounds like you, Stage 3 is where things get really fun.

Will It Still Be Road Legal?

That depends on your parts and setup.

Some Stage 3 builds retain emissions compliance. Others may remove catalytic converters or DPFs, which will fail an MOT and may not be legal for road use.

We’re happy to advise on keeping your car road legal — or tuning it purely for track or off-road use if that’s your goal.

Real Builds from Birmingham

Dan from Sutton Coldfield brought us his MK7 Golf R with a hybrid turbo, forged pistons, and an uprated DSG clutch. After data logging and multiple tuning sessions, we delivered a reliable 480 bhp on 99 octane fuel.

His feedback?

“It’s an animal now. Power from low down and it just keeps pulling. Gear changes snap hard — love it.”

Mark from Halesowen tuned his BMW 335d with uprated turbos, downpipe, and meth injection. We mapped it to deliver over 700 Nm of torque with smooth delivery for daily use.

He said:

“No lag, just endless pull. You nailed the drivability — it’s savage but controlled.”
