IE's Stage 1 ECU Tune delivers an instant increase in performance, leaving no hidden power on the table. In only minutes, Stage 1 will safely max out the factory turbocharger, horsepower, and torque output on entirely stock hardware or maximize the tune with optional bolt-ons (intake, turbo inlet, intercooler).

See the performance tab for power and dyno results


IE Stage 2 software extracts additional power and maxes out the factory turbo by utilizing an upgraded downpipe and performance hardware. Complete hardware upgrades for stage 2 will increase airflow and exhaust flow, reduce turbine backpressure, lower intake air temps, provide faster IAT recovery, and produce a much more efficient and dramatically faster vehicle than the stock hardware and tune. See below for a list of Stage 2 hardware requirements

Upgrading from Stage 1 to Stage 2 or beyond is easy! With IE, you only pay the difference in tune cost with no extra fees. When you install the required matching hardware, follow the instructions on your IE POWERlink app to purchase the tune upgrade, and you will be blowing away the competition in minutes!


IE High Torque ECU calibrations maximize power gains throughout the entire powerband and quickly exceed the torque limitations of the factory DQ250 (DSG transmission) calibration or the stock clutch (manual trans), resulting in clutch slip. Stage 1 and 2 files include an optional low torque for vehicles with stock DSG tunes or clutch. Both high and low torque files are included with your Stage 1 or Stage 2 purchase.

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



To take advantage of your new larger power band, factory rev limiters are raised to 7000 RPM in all stages (will shift slightly before at 6900 RPM on DSG DQ250 equipped cars).

DSG Tune is required to unlock higher RPM, not available for automatic AQ250 transmissions


IE's fully proven software brings track-ready ECU programming to your turbocharged MQB 1.8T engine while retaining factory comfort and reliability. IE's own tuning technology suite completely reverse-engineers the factory ECU mapping, allowing our software engineers 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!  


Enabling the optional Exhaust Crackle feature will add a motorsport-inspired crackle sound to your exhaust note when you free-rev the engine or decelerate. The crackle feature is an included option with Stage 2 and higher.

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