Its with the car in park, even after its warmed up. I could also be injector tick as well, I just thought about that. It isn't LOUD, like its about go boom, but it's just a little noisier than I think it should be for a powertrain with this level of refinement. I hear it with the windows down under initial acceleration, but once it gets to about 2,000 RPM, I can't hear it anymore. I don't think its a problem, as the car runs perfectly and has no shortage of response and power. The gas mileage is actually been better than I expected as well. I actually haven't even launched it off the line yet, or turned off the traction control. I'm easing into that. I want to get a good feel for the handling character before I dive in a do something stupid.
