Quick question regarding boost loss and gaskets...

[awsrock]

Can a leaking intake manifold gasket cause an intial loss in turbo spool up?

I am trying to chase down a symptom I am having with my 87 300D. I won't get into too many details just yet because I have a few more things to try out, but I can't get to those until the weekend and it's killing me!! Is this a possibility? I'd at least like to have some lead to help me not think about it until I can get the manifold off and get the new gasket in!
I cleaned the area today to determine if it was an injector or the intake runner (#2), and I am fairly certain that it is the gasket (I have read that they like to leak around #2)

When I found out that my boost solenoid was clogged, I cleaned it out and had immense power starting around 1900-2000 rpm, but now it isn't coming on until about 22-2400 and isn't quite as strong as before. It *seems* like the boost is buiding where it should, but there is a slight delay..and I feel like I can hear the turbo or air intake a little bit.
