Several employees at my dealer claim it's 100 HP difference before and after the service. I've done full acceleration runs before and after. Not sure it feels 100 HP faster. Maybe because it's having hard time getting the 100 extra HP to the ground? One thing I can say for certain is this car is scary fast once it hooks up. I've had the rear end break loose under full throttle at 70 MPH with the TC turned off.
