Product Details
Perform tune in minutes from the comfort of your own driveway! Only available for purchase in the United States and Canada.
IE Stage 1 & Stage 2 software brings track-ready ECU programming to your turbocharged 3.0L V6 engine while retaining factory comfort and reliability. IE's own tuning technology suite is used to completely reverse-engineer the factory ECU mapping, allowing our software engineers access to realign all safety protocols and sensors for the new performance calibration. Every tune parameter undergoes months of testing on our in-house dyno systems that utilize the world's only Sea Level Generator developed specifically to verify tune operations in any condition. Confidently drive from LA to Pikes Peak with power that will keep you smiling every mile!
IE Stage 2 performance software is a complete engine calibration for full bolt-on stock turbo builds running an aftermarket racing downpipe and catalyst. The unique B9 EA839 engines are equipped with a smaller factory turbo and large stock downpipe with incredibly minimal exhaust restrictions. Using advanced calibration techniques, IE calibrators can extract full peak power on pump gas and ethanol fuels on Stage 1 and 2 downpipe setups. However, the required hardware upgrades for stage 2 will increase airflow, lower intake air temps, faster IAT recovery, and produce an overall more efficient and faster vehicle on the same power.
