After re-reading, I notice you said ALL of the cylinders were at 160-165 except #4. Since this is a relatively new engine, I would not be expecting that greater than 10% drop on just one cylinder. Maybe there is a lifter that is malfunctioning (deflating)once in awhile, giving you that cough you mentioned. For example, if the exhaust valve doesn't get opened on one cycle, there will be residual pressure in the cylinder when the intake valve opens in the next cycle.
