I'm pretty sure with that routing you're going to have no boost control at all. If you don't have a BC, you should only need to hook up one of the lines. I don't have the manual for the Type R, but the fitting on the side should be hooked up to a line between the turbo outlet and the throttle (If this is the one you have Tee'd in to your PS fitting you should be fine).
The nipple on top is used to change the boost setting to something other than what the spring dictates. For instance, if your WG spring is 15 psi, leaving the top nipple open should control boost to 15 psi. If you allow 2 psi to reach the top nipple, you should see 17 psi of boost. If you have this one plumbed in to your manifold, when the turbo hits 15 psi, the top nipple is seeing an additional 15 psi....making it want to control to 30 psi. However, as the turbo increases in boost, the wastegate keeps increasing its setting.
Try pulling/capping the line on your intake manifold and see how it works.

So, what was the deal with the hesitation? And the fix?
