What Is a Stage 1 Remap and Should You Get One?
Thinking your diesel van or car could use a performance boost without hardware mods? A Stage 1 remap might be the answer. It’s a software tweak to your ECU that delivers more power, better torque and improved fuel economy—often within an hour, and all at your location. In this post, we’ll explain exactly what Stage 1 tuning involves, the real gains you can expect, and whether it’s right for your vehicle.
How Stage 1 Remapping Works
Your vehicle’s ECU controls fuel delivery, boost pressure and timing maps. A Stage 1 remap adjusts those parameters safely, within factory tolerances:
- Fuel & Timing: Optimises injector timing and quantity for cleaner, more powerful combustion.
- Boost Pressure: Raises turbo boost to deliver stronger mid-range torque.
- Throttle Response: Reduces lag for a sharper, more immediate throttle feel.
No hardware changes are required—your stock turbo, injectors and intercooler remain exactly as they are.
Typical Performance Gains
While exact figures vary by engine, most diesel vans and cars see:
- +20–40% horsepower (e.g. a 140 bhp engine up to ~190 bhp)
- +25–50% torque (critical for towing and carrying heavy loads)
- 2–4 mpg fuel economy improvement on steady highway runs
These figures come from independent road tests and real-world customer feedback.

Is a Stage 1 Remap Right for You?
Consider a Stage 1 if:
- ✅ You want more responsiveness for daily driving or towing.
- ✅ You seek slight fuel savings on long motorway journeys.
- ✅ You have already addressed any AdBlue faults or engine errors.
- ✅ You prefer a professional, reversible tune over aftermarket hardware.
If you’ve added hardware mods (de-cat, intake), look at our Stage 2 remap instead.
