2019–2024 Audi RS5 2.9T Stage 2 ECU + TCU Package (MG1CS002 / AL552)

Dyno Proven Gains: 390.5 WHP → 480 WHP / 411 WTQ → 545 WTQ

Boost Dynamic Tuning’s Stage 2 ECU + TCU Performance Package unleashes the full potential of the twin-turbo 2.9T Audi RS5. Built around the factory MG1CS002 ECU and AL552 8-speed automatic transmission, this package delivers explosive acceleration, harder mid-range punch, faster shifts, and a more responsive, connected driving experience.

Using averaged real-world dyno data from leading industry calibrations, our Stage 2 calibration produces 480 WHP and 545 WTQ, a massive jump over the stock 390.5 WHP / 411 WTQ baseline. Power delivery is smooth, predictable, and brutally effective on both street and track — with the TCU recalibrated to actually use all of the added torque.

Why Choose Boost Dynamic Tuning?

• U.S.-based tuner specializing in advanced MG1CS002 ECU development
• Transmission calibrations tailored specifically for the AL552 8-speed automatic
• All files developed in-house — no generic off-the-shelf or reseller maps
• Integrated ECU + TCU strategy for cohesive torque management and shift behavior
• Backed by real dyno data and logs — not inflated “crank estimates”
• 100% remote installation with live support directly from your tuner

Stage 1 vs Stage 2 – Which Is Right for You?

Stage 1 ECU + TCU is perfect for a stock hardware RS5 2.9T. It focuses on safe power gains and refined drivability with no supporting modifications required.

Stage 2 ECU + TCU is designed for RS5 owners who have installed supporting modifications such as:

• High-flow downpipes
• Upgraded performance intake system
• Improved cooling / heat management upgrades
• Freer-flowing exhaust

With these upgrades in place, the 2.9T can safely run more boost, more airflow, and more aggressive ignition and torque strategies. Combined with a synchronized AL552 TCU calibration, the RS5 feels dramatically faster — especially from 40–120 MPH and in roll-on highway pulls.

ECU Calibration Benefits – MG1CS002 (Stage 2)

• Real-World Power Gains: 390.5 WHP → 480 WHP / 411 WTQ → 545 WTQ
• More Aggressive Boost Curve: Increased mid-range and top-end airflow
• Higher Torque Targets: Fully realized when paired with Stage 2 TCU mapping
• Refined Fuel & Ignition Maps: Calibrated for reliability, repeatability, and consistency
• Improved Throttle Response: Clean, immediate pedal mapping without “on/off” harshness
• Optional Exhaust Crackle / Overrun: Low, Medium, or High intensity available on request
• Exhaust Valve Strategy: Valves remain open in Dynamic/Sport/RS modes for maximum sound
• Start/Stop Default Off: Engine stop-start begins in the off position
• Launch Control Enabled: Launch behavior can be tailored per customer request

TCU Calibration Benefits – AL552 8-Speed Automatic (Stage 2)

• Raised Torque Limits: Allows the AL552 to fully handle up to 545 WTQ without premature intervention
• Faster Shift Speeds: Quicker, more decisive upshifts and downshifts in Sport/RS modes
• Optimized Shift Points: Keeps the 2.9T in its ideal powerband longer
• Refined Part-Throttle Behavior: Smoother around-town shifting and reduced “gear hunting”
• More Aggressive RS Modes: Sharper logic when you’re driving hard, without ruining daily comfort
• Reduced Kickdown in Manual Mode: Manual mode behaves more like a true manual — fewer unwanted downshifts
• Increased Line/Clutch Pressure: Improved clutch engagement and durability under load
• Improved Launch Control Programming: Cleaner torque application and better 60-foot performance
• ECU + TCU Integration: Both calibrations are designed together for predictable, repeatable performance
