IE's Stage 3 GT2260S TrueFlex for your MK7 or 8V 2.0T utilizes our flex-fuel sensor and harness kit to deliver race gas power on a cost-effective ethanol blend producing a heart-pounding 489HP & 483TQ! E30 is the highest blend available within the fuel system limitations providing the maximum performance numbers without pulling power for higher E%. TrueFlex will automatically adjust between 91 octane up to E30 ethanol blend. Ethanol content must not exceed the maximum E30 blend; an ethanol content sensor kit and gauge is highly recommended.

When selecting a turbocharger for our MQB Stage 3 ECU tuning, IE engineers and calibrators valued a large powerband of increased power and reliability without adding turbo lag. After extensive research and testing, the easy bolt-in design of the German-engineered Garrett GT2260S proves itself as the optimal balance of increased top-end power, smooth power delivery, and responsive boost with unnoticeable lag over stock. Backed by Garretts reputaiton of reliability with over 65 years in leading the proffessional motorsport, aftermarket, and factory turbo applications. When combined with IE's calibration strategies, the result is modern street manners with truly addicting race-car performance.

TURBO SOLD SEPARATELY

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 produced high 10-second quarter mile runs!

IE ECU calibrations are dedicated to perfecting every section of the mapping to deliver a fully realized performance file right out of the gate. Maximized for full performance potential on the drag strip and road coarse while maintaining full comfort and reliability on your daily commute. Get ready to experience IE's Performance Software For your VW GTI, GLI or Audi A3 in only minutes from the comfort of your garage or driveway.  

IE's TrueFlex unlocks the flexibility to run full E85 down to 91 octane gas and any mix in between on a single tune without the need to reflash the ECU. IE's software engineers and calibrators have developed our own advanced TrueFlex calibration, allowing the ECU to safely adjust for ethanol content down to the exact percentage in real-time. This powerful programming brings the ease and confidence to fill up at the pump and make the most power available from your fuel choice without having to drain, verify blends, or reflash the ECU.

E85 TrueFlex is an included option for all model years for stage 1 & 2. IS38 and stage 3 tunes are currently available for 2015-2018 model years only.

Factory equipped flex-fuel calibrations are designed to adjust for the cleanest emissions for different ethanol blends to get the highest MPG. This typically results in maximum timing for the lowest octane (91) across the entire range up to E85, leaving loads of untapped power on the table. IE TrueFlex is a complete performance adaptation that makes instant and continuous adjustments to performance maps such as boost and timing and releases the most available power for the fuel mix as it enters the cylinder.RELIABLE ETHANOL

Not only does IE TrueFlex allow for amazing power potential, but it also offers the most safety from ethanol blends. The ability to truly meter and adjust for ethanol content allows the tune to instantly alter the ECU maps to keep the engine in the optimal range and protect from dangerous lean conditions. This offers amazing protection from pumps that may have lower than advertised ethanol content or if no ethanol is available. Fill up with the best quality fuel available to you, and let TrueFlex do the rest!

The EA888 Gen 3 2.0T engine is not equipped with any type of Flex Fuel systems from the factory and lacks the ability to sense fuel content. In order for IE's TrueFlex ECU tune to work, an IE TrueFlex Sensor Harness Kit is required. This easy to install harness kit installs a sensor capable of delivering instant fuel content data to the ECU calibration.

Ethanol offers higher power output but also requires more fuel delivery than regular pump gas. The stock High Pressure Fuel Pump (HPFP) can not deliver enough fuel to support ethanol and must be upgraded. IE HPFP Upgrade Internal Kit ensures there will be enough fuel supply for ethanol content to run reliably at all elevations and climate conditions safely.
