Stage 1. Dyno-Proven. Reversible.

What a performance remap actually changes

Every car leaves the factory tuned conservatively — built to satisfy emissions rules and cope with poor fuel quality across dozens of markets, not to get the most from your specific engine.

We connect directly to your ECU and rewrite the fuelling, boost and ignition timing maps that control how the engine makes power — tuned around your exact engine, gearbox and fuel.

No engine hardware is changed. Every original map is backed up, so the tune is fully reversible if you ever need it back to standard.

Performance Extras

Take it further

On top of a Stage 1 or Stage 2 remap, these are the extras enthusiasts ask for most. Each is assessed individually for your specific car — we'll always give you an honest read on suitability, road legality and insurance before booking anything in.

Track / Private Road Only

Speed Limiter / VMAX Delete

Removes the factory-set top speed limiter — often 112mph or 155mph depending on the manufacturer — so the car can reach its natural top speed. Intended for track days, private roads, or manufacturer-restricted vehicles being used off the public road network. We'll talk through what's appropriate for how you'll actually use the car.

Check Local Noise Rules

Pops & Bangs

Exhaust note tuning that adds crackle and pop on throttle lift-off — a popular finishing touch for hot hatches and cars with aftermarket exhausts. Some track days and residential areas have noise restrictions, so it's worth checking before you commit to using it regularly.

Road & Track

Launch Control

Holds the engine at an optimum RPM against the brake and releases power in a controlled, repeatable way for the cleanest possible standing start. Popular for track days and drag strips, and straightforward to use responsibly on the road.

Track / Private Road Only

Hard Cut / Popcorn Limiter

An aggressive ignition-cut rev limiter that creates a sharp, theatrical crackle at redline instead of a smooth cut-off. Given how attention-grabbing it is, this is best suited to track days and exhibition use rather than everyday road driving.

Road & Track

Auto / DSG Gearbox Tuning

Faster, firmer shifts and remapped shift points for automatic and dual-clutch gearboxes, including adjusted launch RPM where supported. Makes the car feel noticeably sharper without touching the engine tune itself.

Assessed Per Engine

Rev Limit Increase

A raised rev ceiling to make the most of your engine's natural power delivery, where the internals and valvetrain safely allow it. Not every engine is a good candidate — we'll assess yours individually before recommending this.

Questions

Before you book

Yes. Every original factory map is backed up before we make any changes, so the car can be returned to standard at any point if you ever need to.

Manufacturer warranty terms vary by make and age of car. We'll talk you through exactly what applies to your vehicle before any work starts, and every original map is backed up so a tune can be reversed if ever needed.

It depends on the option and how it's used. Some extras are intended for track or private road use only — we'll give you an honest answer on road legality and insurance implications for your specific car before any work is carried out.

Stage 1 is a software-only tune for a standard, unmodified car. Stage 2 is for cars that already have supporting hardware — intake, exhaust or intercooler upgrades — allowing a higher power ceiling than Stage 1 alone.

No — this depends on the engine's internals and valvetrain, and isn't suitable for every car. We assess this individually and will tell you honestly if it isn't a good fit for your engine.
