to be 17.5% according to Jim C. That equates to multiplying the measured torque by 1.21. Jim C also claims the actual hp to be 250hp and -1/+10% (BMW spec).The dyno is pretty good. And I know we aren't comparing apples to apples here, but we have seen another stock M Coupe put down nearly 220hp at a local dyno day.
