What this service is
What it is
A Stage 1 remap is a custom ECU file written to extract the maximum safe performance and economy from your vehicle in its standard factory form. No intake, no intercooler, no exhaust — just smarter software working with the hardware you already own.
Who it's for
It's perfect for daily drivers, motorway commuters, family hatchbacks, fleet vans, tow cars and 4x4s. If your vehicle is in good mechanical health and on its factory turbo, intercooler and DPF, it's a Stage 1 candidate.
When you need it
When your engine feels flat, MPG is creeping the wrong way, overtakes feel risky, or you simply want the version of the car the manufacturer didn't sell you. Best done after a recent service while the engine is healthy.
Why professional matters
Manufacturers leave 15–30% torque on the table to meet global emissions, climate and warranty bands. A Stage 1 calibrated for UK fuel and South Wales conditions reclaims that headroom safely.
What it costs to ignore it
There are two reasons people regret a Stage 1: they bought a generic file, or they bought it from someone who didn't bother to look at the engine first. Both are avoidable.
Our process
Every stage 1 remap job follows the same disciplined sequence — so the result is predictable, repeatable and guaranteed.
Diagnostic read, live data, visual checks — we won't flash a sick engine.
Stored locally and off-site. Lifetime backup means you can revert any time.
Calibrated for your engine, gearbox, fuel and goal — power, MPG or balanced daily.
Verified on local roads with logging for boost, fuelling and EGT/rail pressure.
You drive away with documentation, before/after notes and the original file safely stored.
What you actually get
Petrol turbos and modern diesels respond strongly to a proper Stage 1.
Where you actually feel the remap — mid-range overtakes, hill climbs, towing.
Available as an economy-biased file for high-mileage drivers and fleet vans.
Pedal mapping refined so the engine feels awake from idle.
Shorter overtakes, easier hills, less gear hunting.
Original file saved forever — back to factory in 30 minutes if needed.
The detail
A Stage 1 is the gateway upgrade for almost every modern turbo vehicle. Here's exactly what it involves and what to expect on common South Wales vehicles.
We rewrite fuelling tables (injection duration on diesel, lambda targets on petrol), boost target and waste-gate/VNT control, torque limiters per gear, smoke and EGT limiters, ignition advance (petrol), and pedal mapping. Emissions-critical strategy and safety limits stay intact.
VW 2.0 TDI 150 → ~190bhp / 400Nm. BMW 320d N47 184 → ~225bhp / 470Nm. Ford Ranger 3.2 TDCi → ~230bhp / 600Nm. Audi 2.0 TFSI 220 → ~285bhp / 410Nm. Ford Transit 2.0 EcoBlue 170 → ~210bhp / 480Nm. Real numbers, written file, not photoshopped graphs.
An economy map prioritises low-load efficiency, leaner cruise fuelling, earlier torque delivery so the gearbox shifts up sooner, and a calmer pedal. Power maps push peak BHP and torque higher. We'll ask what you actually want — most fleet vans and commuters take the economy file, most tow cars take the balanced file.
DPF differential pressure, EGR position, MAF/MAP signal sanity, fuel rail pressure under load, turbo actuator response, glow plug status, clutch slip on manuals, gearbox adaptation values on DSG/ZF autos. If anything is off, you hear about it.
We come to you. Most Stage 1 jobs are finished in 45–90 minutes on a driveway, workplace car park or yard. Travel within South Wales is included in the quote.
