APR A8 4.0T ECU Upgrade vs Stock - Acceleration

Added by AutomotiveUploads
Audi A8 & A8L 4.0 TFSI V8 0-140 MPH acceleration testing.

Gauges show a stock A8L vs the same A8L with an APR Stage I ECU Upgrade using 93 octane fuel.

The APR Stage I ECU Upgrade gives you higher peak numbers of 545 HP / 629 FT-LBS on 93 (R+M)/2 octane and up to 578 HP / 679 FT-LBS on 100 (R+M)/2 octane race fuel. As much as +127 HP and +175 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.
