No; the most likely cause of a tight/loose chain is an off-center chainring. Sometimes you can reduce this by loosening the chainring bolts and shifting the ring's position a little, but some rings are machined far enough off-center that you'll never entirely eliminate it. This is particularly the case with road chainrings, where concentricity is not a major concern. True track chainrings tend to be manufactured to tighter tolerances and often cost considerably more for that reason.
