If you do a TRE, personally, I'd just do it yourself with a 5¢ resistor instead of a $75 one.
You probably won't notice much by dyno tuning a bone stock bike, since it was optimized (give or take production tolerances) from the factory. Its the mods that require fine tuning of the fuel mapping.
On the chain, I'd personally avoid waxes. Almost every day, I place mine on its stand, run a toothbrush with spray lube (WD-40 and the likes) on both top and bottom and then drip gear oil with the wheel rolling. I have 12K on my current chain and it's well within tolerance. It will probably see another 12K before it is replaced. With waxes, I was stretching chains no matter what I did. My method (which is really 'by-the-book' more or less) is messy, but I'd much rather spend my money on gas than premature chain wear (that's an extra 3-4K miles in gas, BTW).
You can also get a Hawk or Scott oiler to automatically lube while you ride... again, a bit messy, but you have to ask, do you ride to ride, or ride to show?

How do you know when the chain is within specs?
Also, I tried the oil and PJ1 route, but here in Nevada, it is so damn dusty that the chain looks like poop after a ride or two. I am JUST using WD-40 now. The chain has less "grit" stuck to it, the bike looks cleaner, and the chain spins free. I guess I fail to see how any lubricant could prevent stretch...?
