I'm not PS or JJ (or I'd already have mine) but, I also would not change the settings or disconnect the ICE when doing the valves or tb's. It probably wouldn't have any effect either way (especially on the valves), BUT I would rather tune the bike in the condition I run it in. In other words, if you synch the tb's without it and then plug it in, it could throw off the synch.
Of course, my opinion is what you paid for it.
