So I did some tweeking and managed to come up with a better version of what I posted earlier.

I did manage to get Chi Wave to work, but it ended up being lower dps because it was eating a global. Chi Wave scales with level AND gear, so I think the reason yours did more was because you were using low level swords which lowered your overall damage but Chi Wave retained its level 90 base damage.
Just make sure you hold ALT when you get 5+ stacks for Tigereye Brew and it should be good to go! If you want it on a separate button that is fine as well, just make sure you remove that line from the macro and hit the button at 5+ instead.
Todd’s Macro DPS iLvL 503: 52,271 DPS

My Macro + Chi Wave DPS iLvL 503: 64,869 DPS
Make sure Invoke Xuen is on your bar for burn phase!
Edit: From Wowhead:
Level 30 Chi Wave
You cause a wave of Chi energy to flow through friend and foe, dealing (0 + 1 * Attack power * 0.45) Nature damage or (0 + 1 * Attack power * 0.45) healing. Bounces up to 7 times to the nearest targets within 25 yards.
When bouncing to allies, Chi Wave will prefer those injured over full health.
Level 90 Chi Wave
You cause a wave of Chi energy to flow through friend and foe, dealing (493 + 1 * Attack power * 0.45) Nature damage or (493 + 1 * Attack power * 0.45) healing. Bounces up to 7 times to the nearest targets within 25 yards.
