You just can't give an opinion on here without insinuating that those that don't agree with you are doing things the wrong way and/or are stupid. If you actually took your own advice (the advice you gave @72bluNblu) you would just stick to the facts and move on. The bottom line with this is there are many using the tensioner with success including engine builders like hughes engines who only do mopar. To the op my advice is to call hughes and Imm or a few other mopar engine builders and see what they say. In the end whatever chain you get if you don't use a tensioner pull the fuel pump in a few hundred miles or so and check the chain, that is the only way to know for sure if it worked out.
