When you pour the soapy water on the hoses, did you just let it sit while the car idles or did you pull on the throttle cable a couple of times? If you are using the soap water test, you have to rev the engine to see the leaks.
Also, make sure your car has a BCC and that it is tuned properly (check mkiv.com for info on how to tune to correct voltage). Without a BCC, your car will hit fuel cut at 1 BAR.
I was experiencing boost leaks and just replaced all the vacuum hoses with silicone ones from Hose Techniques. You wouldn't believe how bad some of those rubber hoses look with 50k miles on them. ~$150 for the kit and I recovered 2 psi of boost
