IE Audi 2.5T 5 Cylinder Turbo Performance ECU Tune | Fits 8V RS3 & 8S TTRS IESOVO22

IE Stage 1

Your factory TSI power plant is controlled by a very advanced Engine Control Unit (ECU). This complicated computer is loaded with maps and routines to operate your vehicle efficiently, however, much of the available performance 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 turbo upgrades. IE's advanced ECU Tunes are extensively engineering to completely reverse-engineer the factory mapping and re-write new calibrations for ultimate performance without sacrificing factory comfort and reliability. These perfected ECU Tunes undergo thousands of hours dyno testing, street analysis, track days, altitude verification and more. Each test results obsessive revisions resulting in a rounded tune that will take your VW or Audi 2.0T TSI engine from "peppy" to "WOW"!
