In many idle tuning guides I've read I see a common trend to give cams with more overlap a lot of 'loving' within the tune.
See the following for examples.

Can anyone help me wrap my mind around what overlap does to idle? I ask because by most tuning guides, my cam with 38 degrees of overlap should be a wicked wild beast to tame, though it's an extremely timid 206/212 (259/265) 112lsa 110icl in an iron block LS1.
