IE 2.5T Stage 1 ECU tune delivers easy performance from your 5 cylinder engine powerhouse with 427-517HP and 488-527ft-lbs of torque from 91, 93, 100, or 104 fuel options. Engineered to operate on entirely stock hardware or with an upgraded intake, turbo inlet, and intercooler for the most performance.

See the performance tab for power results and dyno charts.

IE Stage 2 ECU tune is the next step of power and delivers the most performance potential available when paired with an upgraded performance downpipe. Maximum torque and horsepower gains are realized across the powerband with up to 577HP and 592ft-lbs of torque! Includes 91, 93, 100, 104 and E8 fuel maps.

E85 fuel unlocks the most performance potential from our stage 2 tune and even the ability to run 10s in a quarter mile! 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. Although full E85 is recommended for the highest power output, safeguards are included within the E85 ECU calibration to adjust for ethanol as low as E60.

E85 is an optional fuel map included with Stage 1 & Stage 2 purchase.

E85 requires much more fuel and can stretch the limitations of the factory 2.5T fuel system. IE offers an optional 1000cc injector file included with your tune that allows the installation of larger port injectors. When added to the direct port injectors, the combination allows massive headroom to safely run E85 worry free. Adding larger port injectors is more cost efficient and reliable than an upgraded HPFP and will run on both pump gas and ethanol with a regular idle and stock-like drivability. For best results we recommend the Sharp-Motorsport injector kit.

IE's fully proven software brings track-ready ECU programming to your 5 cylinder engine while retaining factory comfort and reliability. IE's own tuning technology is used to completely reverse-engineer the factory ECU mapping, allowing our software engineers access to match 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!
