Welcome to EBPF!! 
Enjoy the forum! I hail originally from Buda....
Got the mod bug already! Cool, and great mod choices to start!
If I may......
I'd recommend a $52 and 2 minute mod.... A 3BAR MAP (manifold absolute pressure) sensor... Easy!
The DPs will augment the 3BAR turbo mapping by getting turbo spooling earlier (dyno proven on my '13 SHO) getting you the most from them. Tell LMS you want the mods you have included.
The 3BAR MAP and a tune adjusted for it will make an appreciable difference.
I can only address factually the change with LMS. I have v8 with DP, 160
oT-stat, and 3BAR adjustments.
It is worth as much as a .47 sec lowering of the time in the 1/4 mile
and will likely give you a sub 4 sec (improved over 4.2-4.3 sec) 0-60 time compared to the same tune without a 3BAR.... 2 minutes, 1 screw, 1 electrical plug... plus it's right on top of the mainifold... easy. Times quoted are with LMS tunes on SHO and MKS from '10 - '14.
The OEM Ford 3BAR sensor is $52.80 at Tasca. It's the best price I could find when I ordered my back-up 3BAR:

Regardless of what you decide, enjoy that special ride!
