Stage 3 power isn’t something you guess at. To deliver up to 424 HP while keeping safety intact, you have to sweat the details. That’s what iE does best. The iE Stage 3 Map Pack upgrades your Audi B9 A4 factory engine computer with custom programming calibrated specifically for the Turbo Systems Hybrid turbocharger. Smooth, predictable power with none of the harshness, lag, or unpredictability of generic big turbo setups. Maximum power, smooth drivability, and a brutal pull that keeps building long after the stock turbo falls flat.
Every turbo behaves differently, and generic calibrations leave performance on the table or introduce risky, unpredictable behavior. The iE Stage 3 Map Pack upgrades your factory engine computer with custom programming calibrated specifically for the Turbo Systems Hybrid Turbocharger. This means you get maximum power, smooth delivery, and a true no-compromise big turbo experience with a relentless pull to redline and iE-smooth drivability.
Big turbo power should feel exciting, not scary. That’s why iE engineers carefully selected the Turbo Systems Hybrid to deliver maximum safe power on stock engine internals while keeping turbo lag to a minimum. Months of development and real-world testing across different cars, climates, and driving conditions ensure this Stage 3 calibration performs reliably everywhere. Advanced AutoProtect safety logic instantly reduces power if something isn’t right. This is stage 3 power with protection when you need it most.

There is no waiting for an "upgrade license" or back-and-forth emails. When you purchase iE Map Packs, our server identifies your unique POWERlink Serial Number and loads the balance directly to your device via the cloud. No file attachments. No downtime. You simply open the app, and your unlock credits are waiting.
We kept this simple. Just locate the Serial Number starting with "V4" on the back of your dongle and enter it at checkout. Once purchased, connect your POWERlink to the app via Bluetooth. The system will auto-sync via the cloud, and your credits will appear in an hour or less.
No. This is a dedicated software upgrade that requires a pre-existing iE B9 A4 Apex tuning license. It is a separate add-on product explicitly designed for hybrid turbocharger hardware.
No. The Map Pack only includes the ECU calibration required to run the Turbo Systems Hybrid Turbocharger. The turbo and supporting hardware must be purchased separately.
iE B9 A4 Apex Tier, Stage 3 Map Pack Engine Tune and Stage 3 TCU Tune are mandatory to run this turbo safely and correctly on your Longitudinal EA888 Gen 3. The Stage 3 Map Pack expands the Apex tune by adding the programming required to run the upgraded turbocharger to your stock ECU.
Stage 3 hardware requires the iE/TurboSystems Turbocharger, upgraded air intake, 5 Bar map sensors, intercooler, HPFP Upgrade, and VW Golf R injector upgrade (X4 injectors VW PN: 06K906036N and X4 injector clips VW PN: 06J133036F).
Yes. iE’s specific Stage 3 TCU tune is mandatory to handle the increased torque. It optimizes shift points specifically for the hybrid power curve.
Yes. Our calibrations are engineered around smooth, controlled torque delivery rather than dangerous spikes. In addition, iE AutoProtect continuously monitors individual cylinders and actively intervenes if unsafe conditions are detected. Power is reduced automatically and restored once conditions stabilize.
Yes. The Stage 3 Map Pack is installed using the iE POWERlink OBD-II tuning cable and mobile app. Simply connect the cable, select the Stage 3 calibration, and flash the ECU directly from your phone.
Yes. The Turbo Systems turbo and calibration were engineered to deliver maximum safe power on the stock Audi B9 A4 & A5 2.0T engine. Advanced AutoProtect safety programming continuously monitors engine conditions and reduces power if something isn’t right.
The iE Stage 3 A4 Upgraded Turbo Tune can produce up to 424 horsepower on properly equipped B9 A4 and A5 vehicles when running recommended supporting hardware and fuel.
It comes down to control, refinement, and technology. Many off-the-shelf tunes are conservative and locked. Custom tuning often requires weeks of revisions with limited feature support. iE POWERlink delivers professional-grade calibration, advanced safety systems, and in-runtime adjustable features you control instantly from your phone. It’s not just a tune. It’s a live ECU platform.
