Not saying the PW isn't a gorgeous unit or that lowering air temps is bad! I plan on having one someday myself.
Just saying that even with the PW - at 17+ psi you will blow some vac lines off. I used nylon dual locking zip ties torqued tight on all vac lines when I went stage 2 (currently 17.5psi). That or some small hose clamps rather than the weak little spring clamps will do wonders.
Also when you made the comment you didn't have money for a DP and bigger turbo I was sharing what the consensus typically is - bulletproof your OEM TMIC, get a used AVO or Perrin for $400, and invest in the DP and tune first. The DP upgrade with a tune is a great mod dollar for dollar power wise. Going with a badass TMIC is a supporting mod - typically for much larger turbos not stage 1 power levels.
