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 ## The cheap way is the expensive way. 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. ### Real risks - Generic 'Stage 1' files written for another country's fuel and climate. - DPF blockages caused by overfuelled flashes on diesel cars. - Clutch slip on high-mileage manuals when torque is raised without checking the friction plate. - Limp mode triggered by torque limiter mismatches the cheap file never updated. - Wasted money on a flash that's no better than factory — because nothing was actually changed properly. ### Common mistakes - Skipping the pre-remap diagnostic read. - Believing 'one click' OBD dongles can match a custom file. - Ignoring service history and bolting a tune onto a tired engine. - Choosing the cheapest quote with no backup, no road test and no guarantee. Our process ## The steps that make the difference. Every stage 1 remap job follows the same disciplined sequence — so the result is predictable, repeatable and guaranteed. - 1 ### Pre-flight health check Diagnostic read, live data, visual checks — we won't flash a sick engine. - 2 ### Read and back up the original Stored locally and off-site. Safe backup of your original file means you can revert any time. - 3 ### Custom Stage 1 file written Calibrated for your engine, gearbox, fuel and goal — power, MPG or balanced daily. - 4 ### Flash, adaptations reset, road test Verified on local roads with logging for boost, fuelling and EGT/rail pressure. - 5 ### Handover, paperwork & Original file stored safely You drive away with documentation, before/after notes and the original file safely stored. What you actually get ## The outcomes that matter. ### Typical 15–25% BHP gain Petrol turbos and modern diesels respond strongly to a proper Stage 1. ### Typical 20–35% torque gain Where you actually feel the remap — mid-range overtakes, hill climbs, towing. ### 4–8 MPG better economy Available as an economy-biased file for high-mileage drivers and fleet vans. ### Sharper throttle response Pedal mapping refined so the engine feels awake from idle. ### Safer overtaking & towing Shorter overtakes, easier hills, less gear hunting. ### Fully reversible Original file stored safely — restored to  when you bring the vehicle to us if needed. The detail ## Everything you need to know about stage 1 remap. 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. Talk to Gavin Most questions are answered fastest with a quick phone call. 07863 791632 ### What changes inside the ECU on a Stage 1 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. ### Typical gains on common South Wales vehicles 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. ### Stage 1 economy maps vs power maps 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. ### Hardware health checks we always run first 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. ### Mobile coverage across Merthyr Tydfil, Cardiff, Swansea, Newport, Bridgend, Caerphilly, Port Talbot, Chepstow and Cwmbran We come to you.
