Stage 1 remap

A Stage 1 remap is a software-only upgrade for a car on its original hardware. We adjust boost, fuelling, ignition timing, torque limits and throttle response so the engine makes more of the power it was always capable of, within safe limits for the standard turbo, clutch and gearbox.

It suits daily drivers, hot hatches, performance saloons and turbo diesels that tow: stronger mid-range pull, a sharper throttle and a car that feels more alive, without changing a single part. Most Stage 1 remaps are done in a single visit.

Stage 2: £540 inc. VAT

Stage 2 remap

Bolt-on parts only work properly when the map is written for them. Stage 2 is a custom calibration for a car with improved breathing. With the extra airflow, we can safely run more boost, adjust fuelling and timing, and keep temperatures in check, for more power across the rev range and a car that pulls harder for longer. We never use an off-the-shelf Stage 2 file.

Better intake

A less restrictive intake helps the turbo breathe, especially at high revs.

Uprated intercooler

Keeps charge temperatures down so power stays consistent, run after run.

Downpipe or exhaust

A high-flow, catalysed downpipe or freer exhaust lets the turbo flow properly.

Healthy drivetrain

We check clutch, gearbox and engine health. Some cars need a clutch upgrade.

Stage 3: quoted per car

Stage 3 and custom tuning

Stage 3 is for serious builds: a larger turbo, upgraded injectors and fuel system, built internals or a full engine swap. These cars need a calibration written from the ground up and developed on the dyno, not a modified file.

We tune factory ECUs and standalone systems, and can handle the wiring, engine build and fuel system as well, so the whole car is set up to work together. Every Stage 3 job is quoted on the build.

Add-on

Pops and bangs / burbles

Want your car to sound as good as it goes? We can add burbles or pops and bangs to your remap, set up to suit the car and how loud you want it, from a subtle crackle on the overrun to something more lively. It is a software change only, and we can turn it down or remove it later.

Pops and bangs are priced per car, so ask us when you get in touch. They can be added at the same time as a Stage 1, 2 or 3 remap.

02

Health check

We scan for faults and check the car is healthy before any tuning starts.

03

Map on the dyno

A baseline run, then a custom calibration refined under load with live datalogging.

04

Prove it

Final runs and a before-and-after graph showing exactly what changed.

Why Pulse

No generic files. No shortcuts.

Most remaps are an off-the-shelf file written for thousands of cars and sent down a cable in a car park. We write the calibration for your car, then prove it on our in-house Dyno Dynamics DS450 4WD dyno, upgraded in 2026.

Because the dyno drives all four wheels, all-wheel-drive cars such as Golf R, Audi S and RS models, BMW xDrive and Nissan GT-R run exactly as they do on the road. Our workshop at Little Staughton is easy to reach from Bedford, St Neots, Huntingdon, Milton Keynes and Luton.

FAQs

ECU remapping FAQs

Stage 1 is £360 and Stage 2 is £540, both including VAT and both mapped on our 4WD dyno. Stage 3 and custom builds are quoted per car. Pops and bangs can be added to a remap; ask us for a price for your car.

Stage 1 is software only, for a standard car. Stage 2 is for cars with supporting parts such as an intake, intercooler and downpipe or exhaust. Stage 3 covers bigger changes like a larger turbo, upgraded fuel system or built engine, and needs a fully custom calibration.

A well-written remap that respects the limits of the engine, turbo, clutch and gearbox is safe. That is why we check the car first, map it on the dyno with live datalogging, and will not push a car beyond what its hardware can take.

Most Stage 1 remaps are completed in a single visit. Stage 2 takes longer on the dyno, and Stage 3 depends on the build. We will confirm timings when you book.

Yes. We read and keep your original ECU file before any changes are made, so the car can be returned to its standard map if you ever need it.

You must tell your insurer about a remap. Our road car remaps keep emissions equipment such as the DPF, EGR and catalytic converter working, so a healthy car should pass its MOT as normal.

No. On road cars we map around road-legal hardware, such as a high-flow catalysed downpipe. Removing a DPF, OPF or catalytic converter from a car used on the road is illegal in the UK and the car will fail its MOT.

Many standard clutches cope with Stage 1. Some slip once torque goes up at Stage 2 or 3. We check the limits for your car and tell you before the tune if an upgrade is advisable.

Pops and bangs are a software change and do not remove any parts. Very loud or aggressive settings can draw attention and may not suit every car, so we set them up to sensible levels and can adjust or remove them later.

A manufacturer can refuse claims on parts they believe have been affected by tuning, such as the engine, turbo or gearbox. If your car is still under warranty, check the terms before you book.

Yes. We remap turbo diesel cars and vans as well as petrol cars. Diesels usually gain strong mid-range torque, which helps with towing and overtaking.
