What’s new for your B9
Four new ways to drive your B9.
iE tunes with LIVE adjustable features don’t just add horsepower - they transform the driving experience. Connecting to both the vehicle’s ECU - and even installed iE hardware like the NEW S4 valved exhaust - iE tunes with LIVE adjustable features allow drivers to customize their vehicle’s settings - including those usually requiring a specialized code-reading tool - in real-time, through a safe, simple, easy-to-use interface.

New tune feature
LIVE adjustable features
Don’t just change your S4’s tune file. Transform your driving experience.
More than a glorified software update delivering more horsepower, iE tunes transform the driving experience, putting the features and settings that matter most at the driver’s fingertips. Installed at home in minutes with our POWERlink tool, LIVE adjustable features enable drivers to adjust their vehicle's settings - including ones previously inaccessible outside of a calibration shop - on-the-fly in real time, through the POWERlink app or your car’s touchscreen.

CORE, PRO, APEX
Pick features, not files.
Most tuning calibrators only install their adjustable features - if they even offer them - in their Stage 3 tune software…which means drivers would have to invest in the Stage 3 tune and the hardware they require to be able to use them. iE’s tuning suites add features most other brands don’t, and allow you to pick the features you want separately from your power stage.

S4 Valved Catback
Loud when you want it. Quiet when you don’t.
S4 owners love our catback. Some told us there are days they’d rather not announce themselves. So we added valves you run from the iE app, not a remote*, and tuned DroneTrap to cut highway drone while keeping the sound you bought it for.

*Manual valve control requires the PRO tune.
