tuning (low to high) C#, G#, C#, F#, A#, D# 
just tune the entire guitar down half a step, then drop D.   
I usually just play it in drop D, it's easier that way. 

timing is not show... listen to the song 

() - palm mute 
* - harmonic 
/  - slide 

intro: 
D#|----------------------------------- 
A#|----------------------------------- 
F#|----------------------------------- 
C#|----------------------------------- 
G#|-----------------7----------------- 
C#|-(0)---5*--(0)-------(8)-(7)-(0)-3- 

verse: 
D#|---------------------- 
A#|---------------------- 
F#|---------9----------5- 
C#|-0--0--x-x---8-7--x-x- 
G#|-0--0--x-7---8-7--x-3- 
C#|-0--0--x-----8-7--x--- 

pre chorus:  This sounds like a slighty different distortion.   
     It sounds like they might be taking a little  
       distortion off for this riff. 
D#|------------------------------------- 
A#|------------------------------------- 
F#|------------------------------------- 
C#|-5---x-x---x-5---x-x---x-5---x-x---x- 
G#|-5---x-x---x-5---x-x---x-5---x-x---x- 
C#|-5---x-x---x-5---x-x---x-5---x-x---x- 

chorus 
D#|--------------------------------- 
A#|--------------------------------- 
F#|-----7-7-5-5-2-2-3-3------------- 
C#|-0-0-7-7-5-5-2-2-3-3-5-5-7-7-3-3- 
G#|-0-0-5-5-3-3-0-0-1-1-5-5-7-7-3-3-  
C#|-0-0-----------------5-5-7-7-3-3- 

Fill: (this is done at the end of the 2nd and third chorus) 
D#|----------------- 
A#|----------------- 
F#|----------------- 
C#|-1-1-1-1-1-1-1-1- 
G#|-1-1-1-1-1-1-1-1- 
C#|-1-1-1-1-1-1-1-1- 

2nd prechorus:  as I said before, this sounds like a different  
distortion, but it sounds like the normal  
distortion is added on for the harmonics at the 
end 
D#|-----------------------------5*-5*-5*-5*- 
A#|-----------------------------5*-5*-5*-5*- 
F#|----------------------------------------- 
C#|-5---x-x---x-5---x-x---x-5--------------- 
G#|-5---x-x---x-5---x-x---x-5--------------- 
C#|-5---x-x---x-5---x-x---x-5--------------- 

bridge: 
D#|---------------------------- 
A#|---------------------------- 
F#|---------------------------- 
C#|-1--0--x-x----0-1-3-1-0--6- 
G#|-1--0--x-x----0-1-3-1-0--6- after playing the last note, slowly 
C#|-1--0--x-x----0-1-3-1-0--6- slide back down to the first fret. 

the fourth time you are playing the bridge, replace the slide on the 
6th fret with this: 

D#|---------- 
A#|---------- 
F#|---------- 
C#|-0--0--0-- 
G#|-0--0--0-- 
C#|-0--0--0--
