Which to get first? Tuner or 70mm TB?

As to bolt-ons, do the exhaust (2-1/2" X or H-pipe, and catback) first, then tuner, then gears (which I guess you already have), then TB and plenum (if you can only do one do the plenum first), then tweak your tune to the highest octane available. This will get you to 250 to 260rwHP.
An after market CAI will do nothing but lighten your wallet. UDPs, aluminum driveshaft, lightweight flywheel, etc. will free up some torque to the rear wheels while accelerating--but beyond that there's not much that's worthwhile without cracking open the cam covers or going to one or another form of bolt-on power adder (s/c, turbo, juice)...

I have exhaust already. catted xpipe with Magna's. And gears.
Yeah that's that I want to do more mods, but I don't want to go blown with this car...I just want to go to the track and maybe hit mid-13's and be like "yay"

The other change I would recommend, based on my recent experience, is to upgrade the fuel injectors to the FRPP 24lb/h EV6 units. I have not been up on the rollers since installing these, however the butt dyno and my G-Tech both report a good kick in the pants at WOT and in the 4500-6000 rpm range.
You will need to change the injector low and high slopes, breakpoint, and minimum pulse width settings in the tune to use these...

Do you wish to tune it yourself, or pay to have it done?

Are you saying that you don't think your stock injectors were providing enough fuel for your set-up?

I think that the EV6 injectors are providing a quicker action, and an improved spray pattern (improved vapourisation), that has improved combustion efficiency. As an evolution of Bosch's injector technology the lighter weight pintle and lower saturation coil allow more precise fuel control.
