Not compatible with front-wheel-drive (FWD) B9 A4/A5 models or 2021 and newer vehicles, which use the updated EA888 Gen 4 engine.

How to verify your vehicle

NO CORPORATE FILTER

Your B9 A4 & A5 isn’t slow. Audi’s factory programming is holding it back. This iE tune safely reprograms the engine computer, stripping away those limits and replacing them with a new, unchained personality. Experience savage acceleration and custom-coded performance tech that makes your A4 & A5 unhinged when you want it, and civil when you don’t.

GAIN UP TO 424 HP

iE B9 A4 Tuning offers gains of up to 424 HP with hybrid turbo, or 378 HP on stock turbo. Unlike inferior tunes, we deliver power without spikes, twitchy hesitation, or clunky surprises. Acceleration pulls hard, throttle response is exact, and driving behavior is perfected for everyday use. Sophisticated when cruising. Brutal when you floor it.

FAST, NOT RECKLESS

This isn’t a rushed, custom dyno file or a conservative one-size-fits-all tune. iE calibrations are developed over months and validated across real cars, climates, and driving conditions worldwide. Advanced safety logic and AutoProtect intelligent programming continuously monitor each cylinder and pull power instantly if something isn’t right. You get massive power and torque from a tune that dials it back when you need it most.

FULL POWER, NO EXCUSES

All 2021+ and some 2019-2020 A4 & A5 transmission computers are locked. While most tuners reduce output or force “low-torque files,” iE wrote custom engine ecu code to force the transmission to safely accept more torque. This custom code increases hydraulic pressures to increase clutch capacity without a transmission tune. Full power, no compromises.

CUSTOMIZE YOUR SOUND

Turn on Exhaust Crackles to give your Audi A4 attitude with dramatic pops and burbles on decel and shifts. Make instant changes from the app to turn it up, tone it down, or switch it off in real time. Kill the drone or free the beast by controlling your exhaust flaps from the app. The sound you want, exactly when you want it.

NEVER WAIT ON BOOST

Other launch controls only build RPM, then fall straight into lag. iE Anti-Lag Launch Control builds RPM and spools the turbo, jumping you into the lead with hard-hitting, boosted launches. Rolling Anti-Lag (RAL) delivers the same advantage while moving, preloading boost at speed for a lag-free rolling launch. Stay one step ahead with instant RPM adjustments from the app or your cruise control stalk.

ADJUSTABLE THROTTLE RESPONSE

Take command with 15 customizable settings ranging from calm and linear to sharp and immediate. Changes apply instantly from the app, so you can switch from economy to aggressive the moment you want it. One tune, multiple personalities. No expensive pedal control module needed.

Installation

Use the POWERlink Tuner and mobile app to retune your engine and unleash its full power.
