I woudn't bother with the chain, it is a PITA and costs a lot. If you keep the engine cool and with good oil it is not going to be an issue. I changed mine because of the turbo.
If you are going to be removing the head - yes ofc change the chain and check the chain tensioners but otherwise it is obsolete.
I'd like it to, company that originally developed it has been brought and sold a bunch of times in the past few months. The latest company that has acquired it now appears more stable and are stating it will be realest bug free shortly.
