Installing the factory IHI IS20 turbocharger found on 2015-2021 MK7 GTI vehicles offers an easy upgrade to higher boost pressures with power levels delivering up to 301HP & 361TQ on pump gas! This advanced ECU calibration, when combined with the larger IS20 and stage 2 hardware (intake, intercooler, & downpipe), delivers increased powerband and extensive turbo performance.

More than double your factory horsepower with the even larger IHI IS38 turbo upgrade! Installing the factory turbo from a 2015-2021 Golf R or S3 and matching ECU tune delivers a tire-spinning 338HP & 361TQ, providing the maximum performance with the largest powerband possible. Fully transform your unassuming 1.8T engine into a true sports car with an additional 180HP over stock!

Upgrading to a larger turbocharger, ECU tune, and required hardware will deliver the maximum power while staying within the safe power limits of the stock engine internals. IE's calibration and software engineers employed highly advanced tuning practices and equipment to develop a complete ground-up engine management system for the larger turbo's boost profile and powerband. All engine mapping and safety coding have been retained and rewritten for substantial power gains for your larger IHI IS20 or IS38 turbocharger.


Features:
  • Up to 338HP & 361TQ
  • Full calibration for IS20 or IS38 turbo upgrades
  • 91 & 93 pump gas fuel maps

Who is Integrated Engineering?

Integrated Engineering was founded in 2007 in Salt Lake City, Utah. It was started by two brothers Peter and David Blais. The two shared the same passion for racing, and this has jumpstarted the two to create Integrated Engineering. 

The company specializes in manufacturing performance products such as rods, camshafts, valve trains, and Billett accessories. Today, they have become a household name when it comes to performance.

German Car Experts

Integrated Engineering focuses on producing performance products for Audi and VWs. As the experts in these platforms, they are able to pinpoint exactly what parts need to be improved to bring out the best in those vehicles. The company considers not only the performance gain but its reliability as well. Their goal is to turn these vehicles into a better performing machine without compromising its reliability.

Attention to Detail is the Key

To create top quality products, the company carefully studies each design detail using specialized software. This enables them to fine-tune the design before it goes to actual manufacturing. They first test their design in ABS plastic to ensure that all measurements are accurate and on the spot. Once everything has been checked, their performance products are then tested in their in-house engine and chassis dyno machine for long hours to test its performance and reliability.

This attention to detail has enabled their parts to perform in extreme conditions and withstand the punishment usually endured during high-performance applications.
