it is the same problem that I had with my SE when I was trying to put the SE lower intake on my S4 block. There was something there creating a vacuum leak and well I had to put the S4 lower back on because I could not get it after 3-4 tries. So I still say Vacuum but it could be power. Have you checked the pin voltage at the ECU yet?
I tried to call you and charles with no luck. Even texted you!
