Custom ECU tuning
Stage 1 Remapping from £259
A Stage 1 remap unlocks extra power and torque from a healthy, standard petrol or diesel vehicle without requiring hardware upgrades. Every file is tailored to the vehicle, backed up before writing and covered by our lifetime software warranty.
Fully custom software
Your calibration is written for your vehicle rather than applying a generic file.
More usable performance
Stronger torque, sharper response and smoother power through the rev range.
Factory safeguards retained
Stage 1 works with standard hardware and keeps the ECU's protection strategies active.
Usually 45–90 minutes
Most vehicles can be tuned through the diagnostic port; bench work may take longer.
Petrol, Diesel & Van Remapping
Petrol cars
Sharper throttle response, stronger boost and more power across the rev range while retaining factory engine protection.
Diesel cars
More low-down and mid-range torque, easier overtaking and the potential for better economy when driven normally.
Vans and pickups
Useful pulling power under load, fewer gear changes and improved drivability for working vehicles and fleets.

Frequently Asked Questions
How much power will I gain from a Stage 1 remap?+
Typical Stage 1 gains range from 20–40% BHP and torque depending on your engine and factory tune. We'll confirm exact expected gains for your vehicle before booking.
Is a remap safe for my engine?+
Yes — when written by qualified tuners using tested files. We only calibrate within safe factory hardware limits and verify with live logs before handover.
Will a remap void my manufacturer warranty?+
Any ECU modification can affect warranty coverage. If your vehicle is still under manufacturer warranty we recommend discussing it with your dealer first.
Is the remap reversible?+
Yes. We back up your original ECU file before any changes so the vehicle can be returned to stock at any time.
How long does a remap take?+
Most OBD Stage 1 remaps take 45–90 minutes. Bench and boot-mode flashes take longer — we'll confirm the exact duration when you book.
Will fuel economy improve?+
Diesel remaps typically improve MPG when driven normally. Petrol tunes are performance-focused, so economy depends on driving style.
