IE Stage 3 MAP Pack (IS38 Turbo) - VW/Audi / Mk7 GTI / GLI / 8V A3
From Sporty
to Holy $#!%
Real horsepower gains without sacrificing safety only happens when every detail is dialed in. That's what iE does best. The iE IS38 Map Pack upgrades your GTI's factory engine computer with custom programming built specifically for the larger IHI IS38 turbocharger. Smooth, predictable power with none of the harshness, lag, or unpredictability of generic setups. More power, stronger acceleration, and a pull that keeps building long after the stock turbo gives up.
Features
IS38 — The Golf R Turbo
The IS38 turbocharger comes factory-equipped on the Golf R and Audi S3, making it a proven, direct bolt-on upgrade for GTI, GLI, and A3 2.0T engines. Larger than the stock IS20 turbo, it flows more air to deliver a serious increase in power and acceleration. The iE calibration is engineered to maintain smooth drivability and reliability while fully unlocking its potential.
Requires Pro or Apex Suite
This Map Pack requires an existing iE Pro or Apex ECU Tune. It expands your tune with the calibration required to safely run the IS38 turbocharger. Upgrading your tuning options is seamless — simply install the required hardware, open the POWERlink™ app, and your upgrade credits load automatically. You only pay the difference in package cost — no extra fees.

How It Works
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.
Instructions
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.
Frequently Asked Questions
Does this Map Pack include the turbocharger?
No. The Map Pack only includes the ECU calibration required to run the IS38 turbo. The turbocharger and supporting hardware must be purchased separately.
Do I need an iE Tune before installing this Map Pack?
Yes. This Map Pack requires an existing iE Pro or Apex ECU Tune. The Map Pack expands your tune with the calibration required to safely run the IS38 turbocharger.
Is the IS38 turbo upgrade safe for daily driving?
Yes. The IS38 turbo is a factory turbocharger used on the Golf R, and the iE calibration is engineered to maintain smooth drivability and reliability while increasing performance.
What supporting hardware is required for the IS38 upgrade?
Running the IS38 turbo typically requires supporting upgrades such as an intercooler, intake system, and performance downpipe. Always review the hardware guide on this page to ensure your vehicle is properly equipped.
Can I install the IS38 Map Pack at home?
Yes. The Map Pack is installed using the iE POWERlink™ OBD-II tuning cable and mobile app, allowing you to flash your ECU directly from your phone.
Is this Stage 3 tune safe for stock engine internals?
Yes. The GT2260S turbo and calibration were engineered to deliver maximum safe power on the stock EA888 engine. Advanced AutoProtect™ safety programming continuously monitors engine conditions and reduces power if something isn't right.
How much power does the IS38 upgrade make?
With the proper supporting hardware installed, the iE IS38 calibration can produce up to 420 horsepower on MQB 2.0T engines including the GTI, GLI, and Audi A3.
iE vs custom tuning vs staged tunes: which is best for my MK7 GTI?
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.
