Have you tried checking the timing tensioner bearing itself before installing? Any undue play sideways? Usually the tensioner doesn't spins freely when new.

That being said I always use INA tensioner when doing timing works. Even Volvo blue box had INA (OE priced). All these years virtually no issue except once while doing belt retensioning at 600 miles I saw splattered bearing grease inside timing cover. Even then there was never any bearing noise. FCP replaced it with another good part.
