It is true; but the likelyhood that it would be, "seat-of-the pants", noticeable is slim unless it was installed totally wrong.
As long as you install the tensioner correctly...i.e. the plastic guide wheel is in-line with the chain, and the chain has 1/2" of up-down movement on the slack side, you will not notice a loss in performance.
Anything that adds friction to the assembly will result in some loss of power to the rear wheel.
