Apparently edo competition doesn't think 517 horsepower is enough to propel Aston Martin's DBS around. "Not quite enough," as they put it. To remedy the situation, edo did a number on the ECU and breathing situation.
For people new to the tuning concept, that means new air filters, high-flow catalytic converters, and a new remote controlled exhaust system. Result: 550 horsepower and 600 Nm / 442 lb-ft of torque (+30 Nm / 22 lb-ft).
"This is enough power to accelerate from 0 to 100 km/h (62 mph) in 4.1 seconds and continue on to a top speed of 320 km/h (199 mph)." I'll bet it is.
