2.5T EVO Stage 1 & 2

Stage 1 delivers 427–517 HP and 488–527 ft-lbs on 91, 93, 100, or 104 octane, running on entirely stock hardware or more with an upgraded intake, turbo inlet, and intercooler. Paired with a performance downpipe, Stage 2 unlocks up to 577 HP and 592 ft-lbs across the powerband. Upgrading from Stage 1 later only costs the price difference.

E85 & Injector Support

E85 unlocks the most from Stage 2, with the ECU safely adapting for ethanol content as low as E60. An optional 1000cc injector file gives the factory fuel system the headroom to run E85 worry-free, with stock-like idle and drivability on pump gas or ethanol.

Reliability Testing

IE's software brings track-ready ECU programming to the five-cylinder while keeping factory comfort and reliability intact. The mapping is reverse-engineered from the factory ECU so every safety protocol is matched, and every parameter is tested for months on IE's in-house dyno using the world's only Sea Level Generator, built to verify tune operation in any condition.
