IE VW 1.8T TSI Gen 3 Performance ECU Tune | Fits Audi A3 VW Alltrack Sportwagen Golf MK7

VW & Audi 1.8T Gen 3 engines are controlled by an advanced Engine Control Unit (ECU). This powerful computer is loaded with complicated maps and routines from factory to optimize vehicle efficiency over performance. Tons of available power is left on the table and the calibration is not written to take advantage of aftermarket power adders such as cold air intakes, intercoolers, donwpipes and more. IE's ECU upgrades replace these boring stock files with Motorsport ready tunes developed from extensive engineering. Our leading ECU calibrators completely reverse-engineer the factory mapping and re-write new calibrations for ultimate performance without sacrificing factory comfort and reliability. Each performance stage undergoes thousands of dyno tests, street analysis, track days, altitude testing and more -each test resulting in tweaks and revisions to the calibrations. The end result is an obsessively tuned and optimized beast that will completely transform your vehicle to deliver that addictive power you crave.
