As for how tight, you want them just a hair past the point where the noise stops. Thats why I did mine with the engine running, and did them both at the same time. since they both make the same noise, unless you do them both at the same time, if you still hear noise, you have no idea which one is making the noise. I turned mine in and out (be very careful not to back one to far out while the engine is running, it could break the chain, or allow it to jump teeth. I turned both mine in finger tight before starting the engine) several times, probably more than 20, before I developed a "feel" for what was going on, and just what it took to stop the noise, on both sides, and no more. The TOC tensioners have a large head, and you should not need a wrench to tighten them enough to stop the noise. Aside from hearing the noise, you can feel the vibration in the tensioner bolts, and with your fingers on the bolts (not a wrench), you can not only hear it, but you can feel it in the tensioners, and feel the point where it almost stops. Difficult to explain with words, I have been a mechanic all my life, and have finely developed sense of sound and feel. It takes a while to acquire that. But you should still get it close enough, just don't use a wrench on the tensioners. that not only eliminates the sense of feel, but makes it very easy to overtighten them, due to the leverage of the wrench.
Being extra careful not to overtighten them, the first time, after about a week, I heard a slight noise. I readjusted them, it has now been over 15,000 miles and I haven't heard a sound (other than normal engine noise) I don't know any other way to do it, there is no torque spec, because there is no measurable torque. You will just have to use your best judgement. Jerry.
