Breathe New Life into Your Engine,

Safely & Legally

We specialise in mobile engine remap and ECU tuning that unlock hidden torque and sharpen throttle response without compromising reliability. Using licensed calibration software and a rolling library of manufacturer files, we tailor each map to your vehicle, fuel quality and driving style—no generic “chips,” no overnight workshop stay. Most cars gain 15–30 % extra torque and smoother power delivery while often returning better mpg on the motorway.

Call us on 07827533529 or book your remap online to feel the difference on your next drive.

A professionally calibrated ECU engine remapping session raises torque across the mid-range, so everyday overtakes are quicker and hills need fewer down-changes. Unlike cheap plug-ins, our maps keep factory safety limits for boost, exhaust temperature and lambda, protecting turbos and DPFs. Because the tune is loaded through the OBD port, there’s no soldering or risky bench flashing.

Worried about reliability? Each file is dyno-developed and checksum-verified to remain within the engine’s mechanical tolerance. We log inlet temperature, boost and fuelling both before and after the tune to ensure everything stays healthy. If you drive a work van, motorhome or towing vehicle, a torque-focused diesel engine remap can reduce gear-shifts and lower EGTs at cruise—meaning less stress on the drivetrain and DPF.

All maps are written to pass the MOT opacity and OBD checks, and we keep a copy of your factory software so the ECU can be returned to stock at any time. Plus, every mobile engine remap near me comes with a 30-day satisfaction guarantee (Terms & Conditions Apply) (Terms & Conditions Apply) (Terms & Conditions Apply) and free data log review, giving you complete peace of mind while enjoying a more responsive, fuel-efficient drive.

Vehicles We Tune Most

for ECU Remapping Gains

Some engines respond exceptionally well to a calibrated ECU remap, unlocking extra torque, smoother power delivery and even better MPG. Below are the cars and vans we’re asked to tune every week, together with the real-world improvements owners can expect after our mobile OBD remap.

VW Golf 2.0 TDI (150 PS)

Stage 1 remap lifts output to ~190 PS and +60 Nm, giving stronger mid-range pull and up to 2 mpg better cruise economy.

Ford Transit Custom 2.0 EcoBlue

Extra 70 Nm of torque from 1 900 rpm means easier hill climbs when loaded and fewer gear changes around town.

BMW 320d (B47)

Safe power bump from 190 PS to ~225 PS; sharper throttle and 8-speed auto shifts mapped for quicker kick-down.

Vauxhall Astra 1.5 Turbo-D

Torque rise of 55 Nm transforms motorway overtakes and typically delivers 3–4 % fuel-savings at 70 mph cruise.

Mercedes Sprinter 314 CDI

Stage 1 fleet tune adds ~35 bhp and 80 Nm; vans hold sixth gear on gradients, cutting driver fatigue and fuel use.

Peugeot 2008 1.2 PureTech

Turbo-petrol response improves dramatically: +25 bhp, livelier throttle and smoother acceleration from 1 500 rpm.

Why It Matters

Safe Remap, Stronger Drive

A factory map leaves wide safety margins for global fuel quality, altitude and emission targets. Our custom ECU remap recalibrates fuel, boost and torque limits specifically for UK diesel and your driving style. The result is a wider, flatter torque band, quicker throttle response and—when cruising—often better mpg. We log boost, exhaust temperature and lambda before and after, so you know the tune sits safely inside the engine’s limits. If needed, we can flash the ECU back to stock just as easily.

FAQ’s

Have Questions About ECU Remapping?

Straight Answers Before You Tune

What does an ECU remap actually change?

A remap recalibrates fuel delivery, turbo boost, ignition timing and torque limiters. By tailoring those tables to UK fuel and your engine’s safe tolerances, you unlock extra power and efficiency that factory maps leave on the table.

How much extra power or torque will I gain?

Most turbo-diesel cars pick up 25–35 bhp and 50–80 Nm; modern turbo-petrols see 20–30 bhp with crisper throttle. Every file is data-logged first, so gains are matched to your engine’s health and gearbox limits.

Is remapping safe for my engine and turbo?

Yes—when done properly. We keep exhaust-gas temperature, lambda and boost well inside OEM safety margins. Nothing is pushed beyond the hardware’s rated load, so reliability and DPF life are protected.

Will my fuel economy improve or worsen?

Hard acceleration uses more fuel, but at steady cruise many drivers see 5–10 % better mpg thanks to higher torque at lower rpm. Drive the same as before and you’ll likely notice fewer downshifts and smoother motorway economy.

Does a remap affect MOT emissions?

Our files maintain DPF, EGR and SCR functions, so smoke opacity and NOx stay within legal limits. Cars that pass MOT in stock form will pass after the tune.

Can the ECU be flashed back to stock?

Absolutely. We keep a copy of your original calibration and can restore it in minutes via the OBD port—handy when selling the car or returning a lease.

Will my insurance or Warranty (Terms & Conditions apply) be affected?

Insurers may class a remap as a performance modification; we recommend disclosing it. Manufacturer warranties can be voided if a dealer detects the tune, but many owners wait until factory cover has expired or choose our reversible option.

How long does a mobile remap take and what does it cost?

Most sessions take 60–90 minutes on your driveway, including health checks and data logging. Pricing starts at £250 for Stage 1 diesel or petrol tunes, with fleet and repeat discounts available.
