If you're looking to unleash the full potential of your VW or Audi with the MQB 2.0T Gen 3 IS20 Turbo engine, you’ve stumbled onto something special. The IE performance ECU calibration is like a secret weapon for your GTI, GLI, or A3. I've been around the block with these cars, and trust me, this tune takes your ride from a daily driver to a turbocharged thrill machine without compromising on reliability or comfort.

Let's talk about the heart of your MK7. It’s got this sophisticated Engine Control Unit (ECU) that manages a ton of complex maps and routines. But here's the kicker: the factory setup doesn’t fully tap into all the power just waiting to be unleashed, especially if you've added some aftermarket goodies like a cold air intake or a downpipe. That’s where IE steps in. They’ve done the homework and put in the sweat, reverse-engineering the stock mapping to create a new calibration that maximizes performance while keeping that factory feel.

I've seen firsthand how this tune has been tested’think thousands of miles on the street, dyno sessions, and even track days. Each run leads to tweaks and refinements, resulting in a setup that transforms your car into a beast that’s not just powerful but also reliable. You can expect up to 327 horsepower when you pair it with the right hardware upgrades, and it’s designed to work seamlessly with both 91 and 93 octane fuels. Plus, if you’re into that exhilarating RPM rush, they’ve raised the limit to 7000 RPM and removed those pesky road speed limiters.

And for those who love a bit of flair, there's an optional exhaust crackle feature that adds some character to your ride. Just a heads up, you’ll need a performance downpipe and the IE DSG Tune to really make the most of this setup. If you’re running a manual, don’t forget to upgrade your clutch to handle the extra power. They’ve even engineered this tune to perform well in all climates and elevations, so you’re covered no matter where you take your car.

Here’s a quick rundown of what you need to know:

• Requires IE POWERlink Flash Tool and a device running Windows 7 or newer.
• Compatible with IE Cold Air Intake and the IE FDS Intercooler (which I highly recommend).
• Safety protocols remain intact, so you can enjoy the power without worrying about engine life.

As for fitment, this tune is tailored for:

• VW GTI MK7 & MK7.5 (2015-2020) 2.0T Gen 3 (MQB) with IS20 FWD
• VW GLI MK7 (2019-2020) 2.0T Gen 3 (MQB) with IS20 FWD
• AUDI A3 8V (2015-2020) 2.0T Gen 3 (MQB) with IS20 AWD
• AUDI A3 8V (2015-2016) 2.0T Gen 3 (MQB) with IS20 FWD

Just a note: This tune is specifically for 2.0T engines with the IS20 turbo. So if you’ve got an 8V A3 with a 1.8T engine or a 2017+ A3 with FWD, you might want to look elsewhere.

In short, if you want to feel that rush and enjoy a ride that truly reflects the performance potential of your car, this IE Stage 2 Performance ECU Tune is worth considering. It’s been a game-changer for me, and I think it could be for you too.
