Audi RSQ3 Tuning Guide

The Audi RSQ3 F3 (2019 onwards) offers a thrilling driving experience with its 2.5-litre five-cylinder engine and Quattro all-wheel-drive system. As the performance SUV in Audi's line-up, it shares much of its engine and drivetrain architecture with the RS3 and TTRS, making the tuning potential for the RSQ3 F3 very promising. However, when it comes to tuning, there are a few key points and modifications to consider to ensure a smooth upgrade path. This guide will walk you through Stage 1 and Stage 2 tuning options, while highlighting the unique aspects of tuning the RSQ3 F3.

Stage 1 Tuning

Stage 1 tuning is typically the first step for owners looking to unlock more performance from their RSQ3 F3 without the need for heavy modifications. Since the engine and drivetrain are largely shared with the RS3 and TTRS, most Stage 1 upgrades for these models will also apply to the RSQ3. Here’s what you can expect with a Stage 1 tune:

ECU Remap

A Stage 1 remap is one of the most straightforward and effective ways to increase power and improve throttle response. By recalibrating the engine control unit (ECU), you can extract more power from the 2.5-litre five-cylinder engine, with gains of around 40-50 horsepower and 50-70 Nm of torque. A remap will also enhance the engine’s drivability, making it more responsive across the rev range.

Performance Air Filter

Upgrading to a high-flow performance air filter is a simple and cost-effective way to help your engine breathe better. It can improve airflow and slightly boost engine performance, particularly when paired with a remap. While this doesn’t drastically change power output, it can complement other modifications and contribute to a more refined driving experience. JXL Performance recommends the K&N Performance Replacement Air Filter for RSQ3 F3

Upgraded Intercooler

While not always necessary for Stage 1, an upgraded intercooler can be beneficial for maintaining lower intake temperatures, which is especially useful during hotter weather or high-performance driving. This is a good option if you want to ensure your RSQ3 continues to perform optimally in demanding conditions. JXL Performance recommends the Wagner Tuning Audi RSQ3 Evo3 Competition Intercooler Kit

With Stage 1, you won’t be needing any hardware upgrades like a larger turbocharger or exhaust system modifications, making it a relatively simple and cost-effective upgrade.

Stage 2 Tuning

Stage 2 tuning typically involves more significant modifications to the vehicle, aiming for more noticeable power gains. While Stage 2 builds on the groundwork laid by Stage 1, it doesn’t require a turbocharger upgrade. Here’s what you’ll need to consider for Stage 2 tuning:

Downpipe and Exhaust System

A performance downpipe is often the first hardware upgrade when moving to Stage 2. This helps to reduce turbo backpressure and improve exhaust flow, resulting in more power and a better exhaust note. Many RSQ3 owners opt for a high-flow downpipe to complement their remap and turbo upgrades (if they’re part of future plans). You may also consider upgrading the exhaust system, but this depends on your preference for sound and performance gains. Check out our range of downpipes and exhaust systems for your RSQ3 here!

Upgraded Intake System

While a Stage 1 tune can benefit from a simple air filter, a full intake system upgrade is common with Stage 2. An upgraded intake can offer more consistent and cooler air intake temperatures, which, combined with the ECU remap, can yield better performance and throttle response. JXL Performance recommends the Forge Motorsport Carbon Fibre Induction Kit (suitable for RSQ3)

Considerations When Tuning the RSQ3 F3

While tuning the RSQ3 F3 follows a path similar to the RS3 and TTRS, there are a few unique considerations to keep in mind:

• Component Fitment: The RSQ3 F3 is an SUV, and while it shares the same platform and engine as the RS3 and TTRS, some components may need adjustments to fit properly. For instance, exhaust systems or air intake kits designed for the RS3 may not fit directly onto the RSQ3 due to differences in the vehicle’s dimensions. Always ensure that any parts you purchase are specifically compatible with the RSQ3 F3.
• Suspension and Handling: After increasing power, you may find it worthwhile to upgrade the suspension to maintain the handling characteristics of the vehicle. The RSQ3 comes with adaptive dampers, but stiffer, performance-oriented springs or coilovers may be worth considering if you're looking for improved cornering and stability.
• Transmission Considerations: The RSQ3 uses the same seven-speed S-tronic transmission as the RS3 and TTRS, but it’s always important to ensure the gearbox is able to handle the extra torque. Stage 1 and Stage 2 tunes shouldn’t pose a major issue for the transmission, but if you’re pushing the car to higher limits, consider investing in a transmission tune or upgraded clutch packs to ensure durability.
• Warranty and Reliability: As with any tuning, it’s important to keep in mind that performance modifications can impact your warranty and the vehicle’s long-term reliability. Ensure you’re working with reputable tuners who are familiar with the RSQ3’s platform to avoid issues down the road.

Conclusion

Tuning the Audi RSQ3 F3 is an exciting way to unlock more performance from an already impressive vehicle. Stage 1 is a great starting point for those looking for improved power and responsiveness without significant hardware upgrades, while Stage 2 allows for more in-depth modifications to really push the performance envelope.

Given the RSQ3 F3 shares many components with the RS3 and TTRS, the tuning path is relatively familiar, but you’ll need to pay attention to fitment differences and ensure that any aftermarket parts are compatible with the RSQ3’s unique setup. With the right upgrades, your RSQ3 F3 can become an even more exciting and capable machine on the road.
