A Stage 1 remap takes the McLaren 720S from 720bhp and 770Nm to around 820bhp and 880Nm on our rolling road, with no hardware changes. That is a 100bhp step on a car that was already very quick, and it is available because the 4.0 twin-turbo V8 leaves the factory with real headroom. We fitted a Quicksilver exhaust to the same car, which changes the noise rather than the numbers, and it is worth being clear which does which.

Motorsport-exclusive components are explicitly designed for track use. While they can be installed on any vehicle, it’s important to note that using such parts renders the vehicle unsuitable for road use and may result in MOT failure.
No! Our remaps are designed specifically to improve the performance of your vehicle whilst remaining within the tolerances of your vehicles’ components.
Sadly, in attempt to achieve ‘big numbers’ some other companies over tune engines, placing excessive stress on the engine, transmission, cooling systems, etc, leading to reduced life span and reliability of the vehicle. We pride ourselves in producing reliable remaps which do not over stress your vehicle but still produce impressive results.
In any case where a customer is dissatisfied with any ecu remap software supplied, within thirty days of the supply date, the customer can request their money back. In order for any refund to be processed, the customer must present their vehicle to our workshop and allow our technicians to restore the vehicle to its original state. On successful completion JF Automotive will refund the cost of the remap to the customer.
No refund can be granted unless the vehicle is returned to the original state by JF Automotive. The 30-day money back guarantee only applies to stage 1 remaps and does not apply to other services like pops and bangs, parts or dyno sessions.
If another modification is purchased alongside a tuning file, which relies on a remap to operate, only the cost of the file is covered by this guarantee. We reserve the right to withdraw this 30 day money back guarantee.
Absolutely. We offer this service free of charge if the vehicle is brought back to us. We’ll be very surprised if that’s what you want after taking one of our remap products, however in the case of lease cars some customers prefer to put the car back to standard before returning the car. You might want it back to standard if you are visiting a dealer for warranty or service work, again we will do this for free. Should you lose your tuning files due to dealer actions or parts failure we will be happy to re-install the map onto your car free of charge where possible.
No problem, simply bring the vehicle back in and we will take a fresh read of your ECU and write you a new map file free of charge. We offer this as part of our lifetime software support.
Whilst the remap is undetectable to dealer equipment, you should notify your insurance company of any modification to your vehicle. Many insurance companies do not penalise you for upgrades of this nature, particularly if you’re tuning for increased economy however a failure to disclose modifications may invalidate your policy. You may wish to enquire with your insurer if the modification will affect your policy prior to choosing one of our services.
We get asked, “Why do some tuners charge as little as £150?” There are a few factors as to why we do not offer remapping for £100-£200!
We supply custom written files for each vehicle that we remap that take in to account condition, milage and customer request of each vehicle. Our services are fully insured with a 30-day money back guarantee and lifetime support for the tuning software supplied. We constantly invest in the most up to date tuning and diagnostic equipment and software and we offer a quality service to all our customers.
Overall our custom supplied tuning software is of the highest standard that we know of, so if you want the best of the best, choose JF Automotive.
Questions we get asked
How much power does a 720S gain?
Around 100bhp and 110Nm at Stage 1: 720 to roughly 820bhp and 770 to 880Nm, on standard hardware and proven on our dyno.
What does the Quicksilver exhaust add?
Noise, weight saving and appearance. On a turbocharged car an aftermarket exhaust adds very little power on its own, because the turbos are the restriction rather than the pipework behind them. Buy it for the sound, which is a perfectly good reason, not for the figures.
Is 820bhp safe on the standard engine?
On a healthy car with the file written properly and proven on the dyno, yes. We watch boost, timing, lambda and temperatures throughout and stop where the engine tells us to, rather than at a number agreed in advance.
Do you need to remove anything?
No. Stage 1 is software only, so the turbos, exhaust, catalysts and intercoolers all stay exactly as they are. Your original file is kept so the car can be returned to standard.
Will it affect the warranty?
A main dealer can detect a remap and may decline an engine or drivetrain claim as a result. Returning the car to standard before a visit is straightforward and we do it regularly.
How do I book?
Call 01622 321500 or send the registration through. Please book rather than turn up: the car needs the dyno bay for a while and we would rather give it proper attention.
