Changing draw length via a module will not change th nocking point peep, kisser button or anything else. However you may anchor slightly different you might have to relocate the kisser and peep. The tune might change too depending on what arrows you are shooting. Any time you make such changes calls for at least a check of the bow's tune, including shooting broadheads if you intend to hunt with it. There will be a slight speed loss so resighting will probably be necessary, but if you're only talking about an inch then it won't change a lot.
