Fuel Injections? Not Efficenicy?

you could always get a hosetech hose kit and replace all you vacuum lines that might solve your leak...also it is a good idea to upgrade your injectors with your turbo, you will be able to make more power and have less problems with leaning out...however if you go this route you will most like need to get a high flow rail and a pressure regulator such as the B&M so you can tell how much fuel you are actually running...hope this helps.
