If you’re searching for stage 3 remaps in Leicester, you’re not just looking for a bit more power. You’re building something serious.
Stage 3 tuning isn’t for everyone. It’s for drivers and enthusiasts who have invested heavily in hardware upgrades and want a fully customised ECU map to match. At Remap Leicester, we’ve helped build some of the most powerful road and track cars in the area.
If you’ve upgraded your turbo, fuel system, intercooler, and more, we can bring it all together with a map that gets the best from your setup.
What is a Stage 3 Remap?
A stage 3 remap is a custom ECU tune designed specifically for highly modified vehicles. Unlike stage 1 or stage 2 remaps, stage 3 tuning supports major performance upgrades that go beyond bolt-on parts.
This often includes:
- Larger turbo or supercharger
- Upgraded fuel injectors and fuel pump
- Custom exhaust and manifold
- High-capacity intercoolers
- Forged engine components in some cases
With all these parts installed, your factory ECU software can’t keep up. That’s where a full stage 3 custom remap comes in.
Who Is It For?
Stage 3 is for serious performance builds. If you’re pushing your car toward track-ready performance or maximum road power, this is your level.
It’s ideal for:
- Track cars and time attack builds
- Motorsport preparation
- Extreme street performance
- Drag racing setups
- Drivers aiming for 100 to 200 percent power gains
If you’re just looking for better acceleration or more pulling power, stage 1 or 2 may be a better fit.
What Kind of Power Gains Are Possible?
The gains from a stage 3 remap vary massively depending on your build. It’s not uncommon to see power outputs doubled compared to stock.
Examples include:
- A VW Golf GTI going from 220 bhp to over 400 bhp
- A BMW 335d pushing past 450 bhp with the right upgrades
- A Ford Focus ST putting down over 500 bhp at the wheels
We work closely with you to understand your build and your goals. Every map is 100 percent custom, built around your exact modifications and how you intend to use the car.
What’s Involved in a Stage 3 Tune?
This isn’t plug-and-play. A stage 3 remap takes planning, data analysis, and deep tuning knowledge.
Here’s what to expect:
- A full vehicle inspection and hardware review
- Pre-tune diagnostics
- Fueling, timing, and boost pressure optimisation
- Data logging and test driving
- Multiple revisions, if needed
At Remap Leicester, we never rush a stage 3 job. We tune methodically, test carefully, and work closely with you throughout the process.
Is It Road Legal?
That depends on the build.
Some stage 3 remaps will take your car beyond emissions limits for UK road use. Others will still pass MOT with the right supporting components. We’ll walk you through what’s realistic and what to expect if you’re keeping the car on the road.
For track-only vehicles, legality isn’t an issue. We can push things further while still keeping reliability in mind.
What Supporting Mods Do You Need?
Stage 3 is only possible with serious upgrades. This usually includes:
- Larger turbo or hybrid turbo
- High-pressure fuel pump and injectors
- Full turbo-back exhaust system
- Air intake and intercooler
- Clutch and gearbox upgrades
- Cooling system improvements
If you’re not sure if your car is ready for stage 3, get in touch. We’ll assess your setup and let you know exactly what’s needed.
How Long Does It Take?
A full stage 3 remap typically takes a full day, sometimes longer depending on complexity. You may need multiple sessions, especially if data logging reveals the need for map refinements.
We’ll give you a clear timescale before starting and keep you updated throughout.
How Much Does a Stage 3 Remap Cost?
Because every stage 3 job is different, pricing varies based on the time involved and complexity of your setup. As a guide, custom stage 3 remaps at Remap Leicester start from £450.
This includes:
- Detailed consultation
- Full custom ECU remap
- Pre and post-diagnostics
- Test drive and refinement
We’ll quote you transparently before any work begins.
