8V (2015-2017)

At JF Automotive, we specialise in enhancing the performance of your Audi RS3 8V. While tuning the ECU of the current model isn’t possible, our Speedbuster plug-in module is an excellent alternative. This module boosts power and responsiveness without invasive modifications, providing a significant upgrade to your vehicle’s performance.

In addition to the Speedbuster module, we offer and professionally fit high-quality aftermarket parts, including premium exhaust systems. Our exhaust systems not only improve your RS3 8V’s performance but also enhance its sound and your overall driving experience.

Whether you’re looking to boost power, improve responsiveness, or upgrade your exhaust, we have the expertise and products to ensure your RS3 8V operates at its peak.


The RS3, known for its exciting performance and unique five-cylinder engine, combines power and agility perfectly. With its all-wheel drive system and precise handling, the RS3 delivers an exciting drive. By fine-tuning the engine, you can boost its power and responsiveness, to 420 BHP and 620NM of torque, turning the RS3 into a true performance vehicle that excels on the road and track.

Please note this dyno graph shows raw data measured at the wheels. Our system then calculates drivetrain losses to produce engine power figures.

Our custom tuning boosts power and torque to over 420BHP and 620Nm using 99 octane fuel. We achieve this with a fully recalibrated engine management system that significantly increases both power and torque. Our tailored ECU remapping exceeds standard or generic tunes, requiring only a simple installation of our calibration. We connect directly to the ECU through the OBD port for quick programming and the option to easily revert to the original settings.

Extensive testing and revisions on the road and our Mustang 4WD dyno have allowed us to greatly improve power and torque, not just at peak values but throughout the entire rev range, enhancing drivability and expanding the power band.

The tuning process takes about 2 hours. We also offer optional before and after power assessments for an extra fee. Given the significant power managed by the wheels on the RS3, we have finely tuned the performance delivery to maximize traction in each gear.

For this engine paired with the DSG transmission, we provide TCU calibration upgrades to improve torque management, clutch control, and shift performance.

What is motorsport use?

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.

Will the lifespan of my engine be reduced?

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.

What is covered with the 30-day money back guarantee?

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.

Can the remap be reversed?

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.

What if a main dealer wipes the map with a software update?

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.

Do I need to notify my insurance company?

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.

Why we don't you offer ECU remapping for £200?!

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.
