Stage 1 CORE tune
The best dollar you’ll spend on this car.
Ask our Mod Gurus or calibrators to name the one iE tune that changes how a car drives the most, and you’ll likely get the same answer: this one. With an engine that’s nearly identical to the MK8 GTI, the B9.5 leaves the factory as a true AWD sleeper. With this tune, the sleeper awakens…

iE Stage 1 CORE ECU Tune, 45 TFSI
New software
Full power, no TCU flash
Full power. No excuses.
2021+ transmission computers are security-locked, so most tuners lower power to stay under factory torque limits. iE wrote custom engine-side code that works with the factory transmission to safely support the extra torque. You get full advertised power without a low-torque file.
The problem
A locked transmission
The 45 TFSI’s transmission computer can’t be flashed, which caps how much torque a conventional tune can safely send to it.
Our fix
Engine-side torque management
Our calibration talks to the factory transmission so it can handle increased clutch pressure and torque.
What you get
Nothing held back
Full advertised output on stock hardware. No reduced-power file, no TCU tune to buy.
New software
Flash it in your driveway
No mailing files. No waiting.
Other tunes for this platform mean sending files to a tuner and waiting days. iE is the first to offer a B9.5 tune you load yourself. Plug POWERlink into the OBD port, pair the app and flash it in minutes.
Step 1
Plug in
POWERlink V4 goes into the OBD-II port.
Step 2
Pair
Open the POWERlink app on your iPhone or Android phone.
Step 3

A guided, step-by-step flash. No laptop, no ECU removal.
