There are 3 preferred tuners. All 3 have excellent history and results.
Unleashed - tunes remotely via SCT.

AJP - tunes remotely via SCT. contact through this board
Livernois - canned tunes via MyCal.

I am not a fan of 87 tunes. The factory is already an 87 tune that is on edge and pulls timing. To improve performance with 87 fuel generally requires removing safeguards like torque limiting. The little room left in timing/boost adjustments with 87 fuel doesn't justify the money spent on tuning in my opinion.
I should asterisk the above by saying that I would not run 87 even if untuned. Even stock you will have less power and decreased fuel economy. If running 87 is a goal, this is a bad choice of vehicle.
Tuning with 93 will shave more than a second off the quarter mile times and makes the car much more fun overall.
Hit the nail on the head, though I would have put AJP first, as he is super detailed with letting you know what he has changed on revisions, his reasoning, etc.
87 tunes are useless, as he said, and IMO pretty unsafe. 91/93 there is maybe 10-15 hp on the table and probably about the same torque wise, though you can definitely get more once the 93 tune is dialed in.
3 bar is definitely worth it for the $50 or less it costs, as I run 14.5psi/15psi on my tunes and both of those levels are on the edge/past the limit of the 2 bar. CAI isn't really a major difference, but it does look nice, same for exhaust.
I would start by doing an AJP Tune, and 3 bar, and go from there. After tune, the next major improvement can be had from downpipes.
