APR is Pleased to Present the Ultimate ECU Upgrade for the RS6 and RS7 4.0 TFSI!

RS7

The APR Stage I ECU Upgrade gives you higher peak numbers of 674 HP/700 FT-LBS on 93 (R+M)/2 octane and up to 728 HP/744 FT-LBS on 100 (R+M)/2 octane race fuel. As much as +162 HP and +223 FT-LBS of torque are available through the power band! APR’s ECU Upgrade is the best power per dollar modification for the new 4.0 TFSI V8 and gives it just the extra edge these cars lack from the factory without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent car. Read More
