Basically, this is the general consensus on power options.
1) You can run a bootmod3 Stg1 tune. It doesn't require any hardware mods. And I don't think anyone has seen a dyno run with it yet. My crude guess is a 10-20hp increase and a 25-50tq increase.
2) You can do bootmod3 Stg2 tune. This requires an upgraded intercooler and downpipe. Stock intake and exhaust has been said to be adequate. This should get you close to 400 wheel hp and I think 450tq.
3) You can do everything from #2. Plus xdi-35 fuel pump, pure stg2 turbo, and water meth injection. You need a custom tune for this. Then you'll make 450-500whp. Depending on the tune.
There are some little things to add too. Charge and boost pipes, turbo inlet pipe, and diverter valve+. Charge and boost pipes are easier to install while you upgrade the intercooler, so I did mine at the same time. Turbo inlet pipe and diverter valve+ are easier to upgrade when replacing the turbo.
Dinan upgraded turbo is good, Pure Stg2 turbo is better. But I think the Pure turbo is also $1k more expensive.
Biggest benefit I think to upgrade the turbo isn't just the increase in power, but moving the power to higher in the rpm range.
Dinan intercooler is junk. It seems good on paper, but all the logs I've seen on these forums show it running quite hot. Wagner Evo2 Competition I think is the best. There are some other good brands too, but I forgot what they are.
A sport cat downpipe is better than a catless downpipe. Likely no check engine light, still pass emissions tests, and isn't as loud.
Weakest link is downpipe and intercooler, then fuel pump and other fueling related things.

I run the Active Autowerk time and IC. Good combo of you want reliable bump in power without pushing the stock turbo fuel system too much.
