It's going to be so easy to up the boost on the turbo 4 that I'll find it hard to keep from doing it. That being said I will probably do the "easy" things first that won't void the warranty and see how much extra power I can squeeze out of the engine without touching the boost. Things like CAI and from what I can see the exhaust will be a must to replace. I want to replace the stock cat and put in a hi-flo one and then go a single 3" single all the way to the back. I think these few things alone we may be able to pull out an easy 20-40hp without even touching the boost and do it relatively cheaply.
