A system and method for controlling first and second phase shiftable camshafts 44, 46 in a variable cam timing engine 12 and an engine including such a system is disclosed. The method includes determining when the first camshaft 44 is moving toward a first scheduled phase angle with respect to a crankshaft 24 at a faster rate than the second camshaft 46 is moving toward the first scheduled phase angle and slowing down the first camshaft 44 so that the rate of movement of the first camshaft 44 approaches a rate or movement of the second camshaft 46 toward the first scheduled phase angle.
