Upgrading Stages

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. After installing any required hardware, launch your IE POWERlink software and enjoy the next power level in minutes!

Hardware Guide

While no hardware upgrades are required for Stage 1, upgrading the intake, turbo inlet, and intercooler will provide increased airflow, lower intake air temps, and quicker heatsoak recovery for an overall more efficient and faster vehicle.

Part Upgrade

• Stage 1 TCU tune (included) - Required
• Stage 2 TCU tune - Compatible with all stages
• Air Intake - Compatible with all stages
• Turbo Inlet Pipe - Compatible with all stages
• Intercooler - Compatible with all stages
• Heat Exchanger - Compatible with all stages
• HPFP Upgrade - Requires Stage 1+ or Stage 2+
• Cat-Back Exhaust - Compatible with all stages
• Downpipes - Compatible with Stage 2

Technical Features

IE calibration engineers have not only made the engine more powerful, every ECU stage includes extensive adjustments and features to make every bit of the driving experience refined and enjoyable.

Brake Boost

Brake Boosting is commonly used in roll racing, which allows you to build extra boost by applying brake pressure while accelerating. Release the brake pressure for a "rolling launch" or extra power surge.

Brake Boost is included on all tune stages.

Throttle Mapping

IE engineers have mathematically rescaled the entire mass flow model over 30 maps which corrects the entire throttle input range. This extensive remapping work delivers a linear and predictable throttle pedal with clean and linear boost delivery, which improves drivability in any scenario.

Boost Control

The stock ECU, boost control programming is a very "close enough" approach, which works fine in low-boost and stock power output. When increasing performance, this slow response is reflected in the torque curve and can feel erratic on long power pulls. IE calibrators have smoothed the power curve by introducing a new boost control mapping strategy with precision boost request targeting, resulting in unmatched power delivery.

VE Modeling

The factory 2.9T engine's MG1 ECU relies on a complicated volumetric efficiency (VE) model to convert boost to engine load and accurately deliver fuel for various conditions. Instead of depending on fuel correction tables to compensate, our calibrators have remodeled the VE mapping for the new boost/load relationship. This extensive work delivers reliable and proper fueling and smooth power delivery you can feel.

EGT Optimization

ECU programming uses exhaust gas temp (EGT) readings to make air/fuel corrections and determine the health of the combustion cycle. Countless development hours were spent adjusting boost, air/fuel ratio, ignition timing angle, camshaft phasing, intake air temps, and much more to develop the proper EGT adjustments for every octane file.

Enjoy power gains from different fuel options knowing each was individually optimized to provide reliable engine operation without sacrificing power.

IE 2.9T Stage 1 TCU

IE ECU tunes far exceed the torque limitations of the stock RS5 transmission programming, which triggers the TCU to limit power output. The included IE stage 1 TCU tune raises these torque limits while keeping all transmission driving characteristics otherwise stock.

Stage 1 TCU is included with all ECU tunes at no extra charge.
