Save your money on the CAI, once you actually need one, it won't fit an upgraded turbo setup without some modifications.. So you'll need either a new one or a different setup anyway...
Make sure you get a mini max if you ever want to custom tune it or have it custom tuned. Your stock pump is taxed with the stock injectors. Raising them up will just make that situation worse. Also, your stock turbo is maxed out as it is. So either go bigger on the turbo, injectors and pump. Or leave it be for now.
I would look into a fuel rail plug, different theory's on it. But if yours is weak and pops then you will have to do something with it. Fuel filtration is always high on my list. That would be an airdog or fass system.
Otherwise, good start. :thumbsup:
