I would NOT shave the nylon/plastic piece.
A tight chain wont whip/move very far from side to side, the damper has to be tight tolerance to the chain to do it's job, if you shave it down you remove all of that and make it pointless to have it.
The function of it is in it's width. If you shave it and make it narrower you might as well just take it off since you'll cut off the part of it that makes it do it's job.

And for the post about them being machined off center on purpose... all tensioners apply pressure on the slack side. In this picture the tension/touching is on the tension side. The crank will pull the chain down tight, real tight, against that damper if it stays like that and wear right through it. It would be good for it to be centered and it would acceptable if it put light pressure on the slack side, which is the left side. But this style seen here is really meant to sit lightly between both sides.
Any damper or tensioner that is on the slack side has a spring or hydraulic cylinder to apply pressure but not apply solid locked tension. If you've ever done a timing belt then you know the deal here. Or a chain on an overhead cam engine.
If you want a better idea of what I meant about it being sprung and on the slack side look at a picture of a gen 5 (LT engine) tensioner.

EDIT: OK after looking at it, no way would it just bolt on.

Some businesses only deal with email. Phone calls take a long time because people like to ramble, they need to tell you the entire history of their build that has nothing to do with the problem at hand. However most of the time actually talking to someone can figure out a problem faster than emails.

EDIT: Or maybe they did it that way on purpose, so the chain is always supposed to be running against the dampener, no-one would notice 1-2 degrees timing advance.

Sorry bro that's not correct. I saw that video, looks like he put it on backwards too.
If you notice how he started off with the damper the sleeves are installed in it with the flats of them facing forward and he has the side of it that you have facing right, facing right... well those sleeves are supposed to contact the block so he is holding the damper backwards.
Show us "what they specified" because I looked up the install documents on their website and only saw and install doc on the mounting bracket, nothing on the block that goes on the bracket.
And I bet it goes on just fine the other way too. I can't see how it wouldn't. It's two holes drilled to the same size it should flop over no problem.
No it shouldn't be that way. I've been working with timing belts and chains for over 20 years, no manufacturer has ever put anything in the way of the chain on the tension side of the chain. Wouldn't make sense to do so anyway as it would just eat the **** out of the block pulling the chain hard down across the face of the block like that. The chain stays tight on the right side already due to the crank pulling down on the pulley counter clock wise, it flops on the left side.. that's where you want the tension and where every manufacturer ever puts the tensioner
