One of the things I've noticed about this drivetrain in the last three days of driving it is that it seems to be very slow at the revs returning to idle. I would imagine this has something to do with the relative weight of the flywheel or other rotating mass in the drivetrain. Do we have an overly heavy or overly light flywheel that causes this situation? In previous cars I've driven, when you let off the gas, it returns to near idle RPMs 2-3 times faster than with the T-GDI. Any input would be welcome. Thanks!
