can't build boost

[turbo_tomas]

Can't build boost past 6#. I recently upgraded my turbo to a ta-49. All was well for the first few runs, then it wouldn't build more than 6 or so pounds of boost. It seems like there may be a severe leak of some sort on the exhaust side that won't allow any boost to be built. Any ideas?

Check for split / loose hoses at the IC & uppipe and a leaking IC.
