Yeah, I thought about installing my boost/pressure gauge before and after the intercooler a while ago, but didn't have the parts handy. And a plugged intercooler? pffft. Who ever heard of that? The intercooler swap was an easy test, and I was able to pick up a stock one from a friend on a whim. I looked everywhere in the intake and exhaust tract for leaks and restrictions. I only suspected the intercooler because there was nothing else to try.

I ran this setup with LH2.4 for a while. But you can't really monitor airflow very easily with LH2.4. I honestly got more information from looking at the datalogs with Megasquirt. Watching the manifold pressure climb so slowly was enough to tell me there was a leak or restriction somewhere.

Best way to tell would have been to put a gauge or pressure sensor before and after the intercooler. Much easier to swap intercoolers at that point anyway.
