Sorry if I frustrate anyone, but I'm still a little confused about the whole vacuum line, and PCM stuff. So if I do the FM WGA it'll spike 18, and hold at 16? Can I just put the FM WGA on, and spike 18, hold 16, or do I have to do some vacuum stuff, and or PCM stuff? Basically what I want to know is, if I want to have higher boost, and hold a higher boost, do I only need the FM WGA, or do I also have to do other stuff with the FM WGA? Again, sorry if I seem stupid about all this, I just want to do it right because I really like my car. It's my first turbo'd car.
