IE Stage 3 Map Pack Upgrade For B9 Audi A4/A5/Q5 (2017–2020)

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. 

WHEN FAST ISN’T FAST ENOUGH.

Stage 3 power isn’t something you guess at. To deliver up to 424 HP while keeping safety intact, you have to sweat the details. That’s what iE does best. The iE Stage 3 Map Pack upgrades your Audi B9 A4 factory engine computer with custom programming calibrated specifically for the Turbo Systems Hybrid turbocharger. Smooth, predictable power with none of the harshness, lag, or unpredictability of generic big turbo setups. Maximum power, smooth drivability, and a brutal pull that keeps building long after the stock turbo falls flat.

PUSH THE LIMITS, STAY SAFE

Big turbo power should feel exciting, not scary. That’s why iE engineers carefully selected the Turbo Systems Hybrid to deliver maximum safe power on stock engine internals while keeping turbo lag to a minimum. Months of development and real-world testing across different cars, climates, and driving conditions ensure this Stage 3 calibration performs reliably everywhere. Advanced AutoProtect safety logic instantly reduces power if something isn’t right. This is stage 3 power with protection when you need it most.

FEATURES 

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.
