THE BEST DOLLAR YOU'LL SPEND

Factory programming is holding your Audi back. iE tuning safely reprograms the engine computer to unleash savage acceleration, sharper response, and a completely new personality... all backed by AutoProtect. Your A4, A5, or Q5 45 TFSI drives sophisticated when cruising and brutal when you floor it.

THE BEST DOLLAR YOU'LL SPEND

323 HP DONE RIGHT

Big power means nothing if the car doesn't drive right. iE Stage 1 for your B9.5 2.0T delivers up to 323 HP & 391 ft-lbs with smooth, predictable power. No spikes, twitchy hesitation, or clunky surprises found with inferior tunes. Acceleration pulls hard, throttle response is precise, and everyday drivability stays refined.

FAST, NOT RECKLESS

This isn't a rushed one-off 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. AutoProtect continuously monitors critical engine conditions and instantly reduces power when needed. Enjoy massive power with protection built in.

FAST, NOT RECKLESS

FULL POWER, NO EXCUSES

2021+ transmission computers are security locked, forcing conventional tuners to work around factory torque limits by lowering power. iE developed custom engine-side code that properly communicates with the factory transmission to safely support increased clutch pressure and torque capacity. This allows us to deliver full advertised power without low-torque files. No shortcuts... zero compromises.

FULL POWER, NO EXCUSES
