-15 to -20 is normal. the accuracy of ur gauge could be off too. if its mechanical it can be off by 3-4 psi easily. also depends on where u taped into ur vacum line. if ur cars running fine dont worry about it. if its not running up to snuff then look up a vacum line diagram on google and u should be able to find the leak that way
