Tuning the 2.0 TFSi engine – EA113 (& Early EA888)
The emergence of the 2.0 TFSi engine (EA113) marked a significant response to growing concerns about emissions and stricter regulations. This upgraded engine incorporated several critical revisions aimed at enhancing overall efficiency.
Notably, the retirement of the 1.8T engine made way for a more potent turbocharged 2.0 TSi unit. Volkswagen (VW) and Audi adopted turbo-stratified injection, with Audi utilizing turbo-fuel-stratified injection (TFSi), essentially similar technologies.
The standout improvement came with introduction of direct injection, offering precise control over fuel delivery, optimizing efficiency, and boosting performance. This innovation, widely successful in diesel engines, now extends its benefits to petrol engines.
Direct injection not only cools the intake charge but also mitigates detonation risks, enabling higher cylinder pressures and tailored fuel delivery based on engine load.
Range and Specifications of the 2.0 TFSi Engine
The 2.0 TFSi engine, in its various iterations, has become a staple across the entire Audi lineup, establishing itself as the preferred petrol engine. Depending on the model, the power spectrum ranges from 197bhp to 265bhp, with the S3 and TT featuring the highest power variants.
Some engines underwent minor internal revisions and slight adjustments in compression ratios; for instance, the 220bhp BUL engine, as seen in the Limited Edition Quattro, stands out. These engines exhibit heightened responsiveness to custom tunes or remaps compared to their standard counterparts.
A later iteration, the EA888 version, introduced additional port injection, effectively addressing the carbon build-up issues reported in the earlier EA113 version. This evolution showcases Audi’s commitment to refining performance and addressing potential concerns in subsequent engine releases.

Turbocharger Upgrade:
Upgrading the turbocharger or adding a larger one can significantly boost the A4’s performance by providing more air to the engine.
Performance Intercooler:
A larger and more efficient intercooler can cool the compressed air from the turbocharger, preventing heat-related power loss and improving overall engine performance.
High-Flow Fuel Injectors:
Upgraded fuel injectors ensure a proper fuel supply, especially when the engine demands more fuel at higher power levels.
Performance Brakes and Suspension:
With increased power, upgrading the brakes and suspension is essential for maintaining control and ensuring safety during spirited driving.

Quality Engine Oil and Maintenance:
Using high-quality synthetic oil and adhering to a regular maintenance schedule is crucial to ensure the engine’s longevity and optimal performance.
Dyno Tuning:
Utilizing a dynamometer (dyno) for fine-tuning after modifications ensures that the vehicle performs optimally and safely.
Professional Installation:
Many modifications, especially those related to the engine, should be done by experienced professionals to ensure proper installation and avoid damage.
Always remember that modifying a car may impact its warranty, and it’s vital to comply with local regulations. Additionally, modifications should be done responsibly, considering safety and environmental factors.

Why don’t you want to put an atmospheric dump valve in your 2.0 TFSi?
There might be a misunderstanding in your question. Atmospheric dump valves, also known as blow-off valves or diverter valves, are often added to turbocharged engines to release excess pressure from the turbocharger when the throttle is closed, preventing compressor surge and prolonging the life of the turbo.
These valves release the pressurized air into the atmosphere or the intake system. However, there are debates and considerations regarding installing atmospheric dump valves on specific engines, including the 2.0 TFSI (Turbo Fuel Stratified Injection) engines.
Some argue that installing atmospheric dump valves on cars with mass airflow sensor (MAF) systems, joint in many modern engines, can lead to issues. The sudden release of pressurized air can cause the MAF sensor to misread the airflow, leading to potential drivability problems and engine management issues.

The K03, K03S, and K04 turbochargers’ 2.0TFSi user manual
The K03 turbo, prevalent from 1996 to 2000, set the stage for subsequent improvements in Audi 2.0T engines. Its replacement, the K03s, brought increased pressure. This article explores the transition to the more powerful K04 turbo, examining its variants and impact on engine performance.
Comparison of K03 and K03s Turbos:
The K03 turbo, capped at 0.6 bar, characterized the 2.0T engine, equipped with an MAF sensor, cable-operated throttle, and smaller injectors. In contrast, the K03s, featuring 0.8 bar pressure, introduced advancements like MAP sensors and drive-by-wire throttle, enhancing response, fuel economy, and overall performance.
K03 vs. K03s Power Output:
The K03 turbo, with 12 blades, can achieve 200bhp with suitable upgrades. Its successor, the K03s, equipped with 8 blades, boasts a power range of 220 to 250bhp. Driving these turbos hard requires air intake and intercooler upgrades for optimal performance.
Introduction to K04 Turbo:
The K04 turbo, larger in size, offers three variants catering to different engine layouts. Notable differences include temperature gauge holes in the casing, with K04-023 featuring a temperature gauge aperture. Remapping the 2.0TFSi engine can push the base power to approximately 250bhp, and with tweaks, the K04 can reach around 300bhp.
