TT will give the maximum peak horsepower, but the drawbacks from my point of view are:

1) Very complicated compared to NA or SC. Lots more parts, a lot more to monitor and tweak, a lot more little things can fail over time, engine bay a whole lot more crowded, etc.

2) Probably makes more power than I really need if I get a big kit, and a small TT kit is probably within range of an SC's power increase anyways.

3) Turbo Lag. Doesn't matter going for max highway speed or dyno runs, but that's not my focus. I'm just not a fan of the way a TT car feels/responds when trying to finesse a car through corners in traffic and such. SC is more consistent and smooth in this regard.

Everyone has different priorities though, and for some TT might be just what they're looking for. For me, I'll either stay NA or go SC, depending on how relatively cheap/simple/reliable the vendor(s) can make the SC kits.

Edit: and yes, I've done all my own work so far. Nobody has turned a wrench on my car but me [well, me and a couple friends in the case of the header install], although I did have to go to an exhaust guy over the crossmember clearance issue, but he didn't turn wrenches, he just lit up a torch and got out a hammer. One thing I'll definitely be using someone else for is mounting/balancing tires, and setting up my alignment. Oh and having some custom stuff fabbed for the trunk (to give me more cargo room with the spare/sub gone and fit over my battery box, etc). Beyond that though, I'm going to try to do it all myself.
