Integrated Engineering - IE Audi 2.0T TSI Gen 3 Performance ECU Tune | Fits Audi B9 A4 & A5
The B9 A4 and A5 platform is built for more than Audi lets on. The iE POWERlink Tune lifts the factory ECU's restrictions and replaces them with a precision-engineered calibration developed over months of real-world validation —not just a dyno number, but a complete driving transformation.
Factory programming is conservative by design. iE's ECU recalibration targets every layer of that conservatism —boost pressure, ignition timing, rev limits, throttle mapping —and replaces it with a calibration tuned to extract genuine performance from your EA888 Gen 3. The result: up to 378 HP on stock hardware, or up to 424 HP with a hybrid turbo. Power that pulls hard, holds clean, and behaves like it was engineered from day one.
iE's AutoProtect system runs continuously in the background, monitoring each cylinder in real time. If conditions drift outside safe parameters, it pulls back instantly —automatically. You're not just getting more power; you're getting power with a built-in safety net that works every time you drive.
Many 2019–2021 B9 transmissions can't be flashed. Most tuners respond by reducing power targets. iE wrote custom torque management code that forces the transmission to safely accept higher output without a TCU flash —increasing hydraulic clutch pressure on the engine side so you get full advertised power, no compromises.
The POWERlink Mobile device flashes your ECU wirelessly via the iE iOS/Android app. But the real advantage is what comes after the flash: real-time, in-app adjustability with no reflashing required.
Factory launch control revs the engine —that's it. iE Anti-Lag Launch Control pre-spools the turbo so you hit the line with boost already building. Rolling Anti-Lag extends that advantage while moving, preloading boost for instant power delivery from any speed. Adjust launch RPM in real time from the app or your cruise control stalk.
With iE TrueFlex hardware and fueling upgrades, the ECU reads ethanol content in real time and adjusts boost, timing, and fueling automatically. Run 91, 93, E30, E85 —or anything in between. No separate maps. No reflashing. Just fill the tank and drive.
ECU-only upgrade on stock hardware. Gains of up to +52 HP on 91 or 93 octane. Available with an optional Transmission Tune (2017–2020 models) for improved shift speed and overall drivetrain feel.
Pair with an intake, intercooler, and downpipe to safely push the stock turbo to its ceiling —up to 378 HP. Add a catback exhaust to take full advantage of adjustable crackle settings.
Bolt-on iE/TurboSystems Hybrid Turbo, HPFP upgrade, 5-bar MAP sensors, upgraded injectors, Stage 3 Map Pack, and Stage 3 TCU tune combine for up to 424 HP —a full hybrid turbo build with serious mid-range torque and top-end pull.

In-Stock Products
In Stock
Items marked as "In Stock" are physically in our facility, so they're ready to ship when the order is placed. If all items in your order are "In Stock", then your order typically ships within one business day.
Other Availability Modes
We use several availability modes to most accurately identify when products will leave their home facility:
Direct Ship This product is available and will be sourced from one of our suppliers. It may take up to three business days before it ships.
Warehouse Transfer We receive the item, then we ship it to remain on time with the guaranteed delivery range chosen at checkout. It typically takes between 6 and 12 business days before it ships.
Discontinued - No longer available This product has been discontinued by the manufacturer and is no longer available.
We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.
Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.
Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".
A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.
"MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
