APR TCU Transmission Performance Tune For B9 Audi AL552 8HP55 ZF8

APR's TCU Upgrade dramatically improves upon the transmission's function, drivability, and performance through a myriad of enhancement and custom features. Normal daily driving is smoother as we've improved upon the normal quirks and complaints associated with the driving experience. Sporty driving is far more capable with increased torque capacity, clamping pressure, torque management during shifts, AMAX in all gears, and optimized shift point! Both scenarios are optimized to deliver faster acceleration by matching the power output delivered by our ECU Upgrades. Lastly, the software loads to the factory TCU through the OBD-II port, resulting in a clean and headache-free install.

Features:

• Faster up and down shifts in all modes
• Optimized shift points for faster acceleration and smoother driving
• Shift points for both stock and big turbo setups (B9 S4/S5/SQ5) at no additional charge
• Increased maximum allowable torque for higher output
• Increased clutch clamping pressure to hold more torque
• Optimized torque management during shifts for smoother and stronger shifts
• AMAX maximum acceleration shifting mode enabled on all gear shifts
• Manual mode auto 1-2 shift disabled
• Increased maximum RPM on big turbo software (B9 S4/S5/SQ5)
• Works perfectly with our ECU Upgrades
• Flash counter does not increase with each flash
• Direct OBDII port flash (No TCU removal)
• Free lifetime updates
• 30 day money back guarantee
