IE Stage 1 ECU calibration dramatically increases performance leaving no hidden power on the table, and safely maxes out the factory turbocharger's horsepower & torque capability. Engineered to operate on entirely stock hardware and compatible with basic bolt-ons (intake, turbo inlet, intercooler).

See the performance tab for power and dyno results

IE Stage 2 software is for full bolt-on stock turbo builds running an aftermarket racing downpipe and catalyst. IE calibrators use advanced tuning strategies to extract additional power and account for the increased flow from an upgraded downpipe and performance hardware. The required hardware upgrades for stage 2 will increase airflow, exhaust flow, lower intake air temps, provide faster IAT recovery, and produce an overall more efficient and faster vehicle on the stock turbocharger. See below for a complete list of Stage 2 requirements.

IE High Torque ECU calibrations maximize power gains throughout the entire powerband which quickly exceeds the torque limitations of the factory DSG calibration (auto trans) or the stock clutch (manual trans) that leads to clutch slipping. Stage 1 and Stage 2 files include optional Low Torque files for vehicles with stock DSG tune or stock clutch. Both high and low torque files are included and can be switched between as often as you like.

High Torque files require the additional purchase of a DSG transmission tune or clutch upgrade.

E85 fuel unlocks the most performance potential from our ECU tunes for your Golf R or S3 Gen 3 engine. Ethanol contains tons of oxygen, burns cooler, and has a high resistance to knock. This provides more horsepower and torque than running conventional gasoline and is more readily available (in most states) and less expensive than race gas. IE TrueFlex tunes take this a step further and allow for 91 octane all the way up to full E85 or anything in between on one tune without the need to reflash! TrueFlex is an included option with all stages (2015-2017).

To take advantage of the new larger power band, factory rev limits have been raised to 7000RPM in all stages. On DSG equipped cars, the transmission will shift slightly before the new engine RPM (6900RPM).

DSG Tune is required to unlock higher RPM.

Brake Boosting provides a competitive edge in a roll racing scenario. While maintaining a constant speed and throttle position, apply brake pressure with the left foot to build boost at speed resulting in a rolling launch when brake pressure is released.

Enabling the Exhaust Crackle feature will add a motorsport-inspired crackle sound to your exhaust note when you free-rev the engine or decelerate. This feature can be flashed on or off at will with your IE POWERlink.

For the most aggressive pops and bangs an aftermarket catback system is recommended.

IE's fully proven software brings track-ready ECU programming to your IS38 turbocharged 2.0T 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!
