IE Performance ECU Tunes for Audi B9 3.0T S4, S5, & SQ5

iE Stage 1 ECU calibration is a simple flash-only upgrade that delivers instant excitement, providing a broader powerband, a higher rev limit, and increased boost pressures that result in significantly faster 0-60 times and improved acceleration. This advanced calibration can be installed on a completely stock car, and it will adapt to take full advantage of intake and intercooler upgrades.

• Recalibrated factory boost gauge displays higher boost
• Neutral/park rev limit raised to 6500 RPM
• Road speed limiters removed
• Brake boost enabled for rolling launches
• Auto-start/stop defaults to off (can be turned back on)
• Includes advanced TrueFlex ethanol (requires hardware)
• Shielded by iE AutoProtect

Stage 2 Tune

The B9 3.0T engine comes equipped with a large and efficient factory downpipe, which does not impede power or exhaust flow with the stock turbo. While this platform doesn't yield additional power gains on Stage 2 tunes, Stage 2 provides the necessary ECU calibrations to support aftermarket downpipes. This is ideal for users seeking a more aggressive exhaust note and includes an enhanced exhaust overrun/crackle feature in dynamic drive mode.

• More aggressive overrun/crackle in Dynamic mode
• Crackles enabled for free revving in park or neutral
• Includes advanced TrueFlex ethanol (requires hardware)
