Installing your Garrett PowerMax GT2260S, IE Stage 3 ECU tune, and required hardware will deliver the maximum amount of power supported by the fuel system while staying well within the safe power limits of the stock engine internals. IE calibration and software engineers employed highly advanced tuning practices and equipment to develop a complete ground-up engine management system for the unique characteristics of the new boost profile and powerband. All performance calibrations and safety coding has been retained and rewritten for the substantial power gains from the larger Garrett turbocharger.

IE calibrators performed extensive mapping rework for the larger turbo. The countless testing hours of every tune iteration have gone through thousands of dyno tests, street-tested, pushed on the track and expanded to a large beta testing community. This testing process produces a massive library of data from various vehicles, fuels, climates, weather conditions, and altitudes. That data is then used to make numerous changes to the files to maximize performance, driving characteristics, and reliability. In an early beta tune track test, the results proved to produce back-to-back 10 second quarter mile runs!

The stock IS38 turbo begins to fall off and lose power in the higher RPM range, whereas the larger GT2260S turbo continues to make higher power to redline. The factory rev limits have been raised to 7000RPM for Stage 3, providing stronger acceleration and pull in the higher powerband over a Stage 1 or 2 car at the same RPM. DSG cars will shift slightly before the engine redline at 6900RPM.

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.

Stage 3 files include optional exhaust overrun/crackles for an aggressive motorsport sound when you free-rev the engine or decelerate.
