Why it matters

Real figures.
Not guesswork.

Plenty of places will sell you a map off a laptop. Every car here gets a health diagnostics check before we touch the ECU, and our 4WD rolling road is on hand to prove the numbers - before-and-after dyno runs are an optional extra with any tune.

The full set is on Google - here are three that sum it up.

★★★★★

Booked in for a Stage 1 and came away with printouts of the before and after runs. No guesswork, no salesman - just the numbers.

★★★★★

Went in for a service, they spotted a worn bush on the ramp and showed me before doing anything. That is why I keep going back.

Drove down from London for the dyno. Worth the trip - the car pulls properly now and it still drives like a normal car around town.

Car tuning and ECU remapping in Kent

JF Automotive is an independent car tuning and ECU remapping specialist based in Maidstone, Kent. We have remapped more than 50,000 cars since 2011, everything from a Fiesta to a Lamborghini, and every performance job is proven on our own 4WD rolling road rather than signed off on a laptop. If you are searching for remaps, chip tuning or car tuners near you, this is what we do all day, every day.

Whether you want a Stage 1 remap for better economy and drivability, a Stage 2 or Stage 3 build around uprated hardware, gearbox tuning, or a switchable map you can turn on and off from the driver’s seat, we will show you the real power and torque figures for your exact car before you commit to anything.

More than engine tuning

Plenty of customers come to us for a remap and stay for everything else. We are a full workshop: car servicing to manufacturer schedules, mechanical repairs and diagnostics, wheel alignment, air-con regas, gearbox oil changes and Autowatch Ghost immobiliser fitting. Same ramps, same technicians - which is why we can spot a problem during a service and tell you about it before it turns into a bill.

Why use an independent tuning specialist

A main dealer fits whatever the manufacturer signs off. As an independent tuning shop we can look at your car on its own merits: what it makes now, what it should make, and what it needs first - whether that is a straightforward remap or wider car modification around uprated hardware. Every remap is written for the individual vehicle, backed by before and after dyno runs and a 30-day money back guarantee.

Common questions

Where can I get remapping near me in Kent?
We are in Maidstone, a few minutes from junction 7 of the M20, and we cover the whole of Kent - Medway, Ashford, Sittingbourne, Tonbridge, Canterbury, Sevenoaks and Dartford are all within easy reach. If you would rather not travel, our mobile tuning service comes to you.
How much does a remap cost?
It depends on the engine and what you want from it. Put your registration into the box at the top of this page and the tuning builder will show you the Stage 1, 2 and 3 figures for your exact car along with the price - no phone call needed.
Is remapping safe for my engine?
A properly written map is. We work within the safe limits of the standard hardware, check the car on the ramp first, and run it on the dyno before and after so nothing is guessed. Where a car needs hardware before it can take more power, we say so rather than sell you a Stage 2.
Will a remap affect my warranty or insurance?
A remap will not usually void an entire manufacturer warranty, but it can affect a claim on related components, so check your own terms. You should always tell your insurer about a remap - most will cover it, and not declaring it can invalidate the policy.
Can you tune vans, motorhomes and fleets?
Yes. Vans and Sprinters are a big part of what we do, and we handle motorhomes and fleets and taxis as well - usually for drivability and economy rather than outright power.
Do you do servicing as well as tuning?
We do. Servicing, repairs, diagnostics, alignment and air-con all happen in the same workshop. Plenty of customers only ever come to us for a service.
