It is a separate add-on product explicitly designed for hybrid turbocharger hardware.*
Stage 3 power requires calibration built for a specific turbocharger — not a generic big-turbo tune applied broadly and hoped for the best. The iE Stage 3 Map Pack is a custom ECU recalibration developed specifically for the TurboSystems Hybrid Turbocharger on the B9 A4 and A5 2.0T platform. The result is maximum safe output from the hybrid turbo system with the smooth, predictable delivery and real-world reliability that iE’s calibrations are known for. This is the calibration that completes the Stage 3 B9 A4/A5 build.
TURBO-SPECIFIC CALIBRATION
Every turbocharger has unique flow characteristics, boost response, and power delivery behavior. Generic calibrations leave performance unrealized and introduce avoidable risk. The iE Stage 3 Map Pack is calibrated specifically for the TurboSystems Hybrid Turbocharger: fuel delivery, ignition timing, and boost management optimized for maximum safe output from this exact hardware. Relentless pull to redline. Smooth, confident delivery throughout.
REAL-WORLD VALIDATED. ACTIVELY PROTECTED.
iE Stage 3 calibrations are developed over months and validated across multiple vehicles, in varied climates and real driving conditions. Advanced AutoProtect logic monitors engine parameters continuously and reduces output instantly if conditions move outside safe limits. Stage 3 performance, with the protection layer that aggressive calibrations typically skip.
