Ecotune Software Stage 3 - Audi S4/S5 B9 Hybrid Turbo

Ecotune Stage 3 Performance Software: Easy Guide

What is Ecotune Stage 3 Software?

Ecotune Stage 3 Software is an advanced tune for cars with major hardware changes.

Unlike Stage 1 or Stage 2 (which use mostly factory parts), Stage 3 is made for vehicles with upgraded turbos and other parts. It helps your car reach its highest potential.

Stage 3 software gives you:

• A big jump in power (horsepower and torque).

• Better turbo start-up (spool) and power delivery.

• Improved control over boost, ignition, and fuel.

• Better performance at high engine speeds (RPM).

• Better efficiency when you drive hard (with the right parts).

The Ecotune team tests all Stage 3 tunes. This ensures you get maximum power while keeping your car safe and reliable.

Expected Power Gains

Note: Actual numbers change based on your car model, turbo size, parts used, fuel type, and the car's general condition.

Typical Stage 3 improvements are:

• +80 to +200+ horsepower more than Stage 1 (depending on your turbo).

• +100 to +250+ Nm more torque.

• More power is held at high RPM because the new turbo works better.

• Faster gas pedal response and stronger mid-range pull.

• More power at the top end, where factory turbos limit performance.

We confirm the final power gains after we check your car's parts and health.

Must-Have Parts for Stage 3

To handle the extra air, heat, and fuel needed, you must have these parts (or they are highly recommended):

Turbo & Airflow

• Upgraded turbocharger (a bigger or hybrid unit).

• High-flow cold air intake.

• High-flow turbo inlet pipe.

• Upgraded intercooler (often front-mount).

• High-flow charge pipes (may vary by car).

Fuel System Upgrades

• Upgraded Low-Pressure Fuel Pump (LPFP).

• Upgraded High-Pressure Fuel Pump (HPFP).

• Bigger fuel injectors.

• Optional: Parts that work with E85 fuel if you plan to use it.

Exhaust & Flow

• High-flow downpipe (sport cat or decat, only where legal).

• Upgraded exhaust system to handle more flow.

• Optional: Bigger intercooler outlets or boost pipes.

Other Recommended Parts

• Oil catch can or PCV upgrades.

• Upgraded engine mounts.

• Performance clutch or upgraded DSG/TCU software (for high torque cars).

• Improved cooling parts (oil coolers, better radiator) for hard use.

Stage 3 Inspection Rules

Before we start tuning, we must do a full pre-tune inspection. This check is crucial:

• Safety Check: Stage 3 tuning puts a lot of stress on your engine and fuel system. The check makes sure your car is mechanically sound and safe for this high level of tuning.

• Part Verification: Stage 3 software needs specific performance parts. Wrong, broken, or mismatched parts can lead to poor power or engine damage.

• Accurate Tuning: Knowing your exact parts lets the Ecotune team build the perfect software for best power and reliability.

• Preventing Problems: Finding issues before tuning saves you time, money, and stops possible mechanical failures when driving under heavy load.

In the pre-tune check, we confirm all performance parts are fitted correctly. This includes, but isn't limited to: Turbo, Air Intake, Fuel Pumps (LPFP and HPFP), Injectors, Intercooler, and Exhaust components.

Software Sign-Off

The Ecotune Calibration Team must review and approve all software. Your car will not be released with the new tune until this sign-off is complete.

If you must take the car before approval, we will return it to the stock (factory) software.

Note: Although not required, we recommend a pre-tune inspection for Stage 2 tuning as well.
