OK.. Changed all vac hoses from MAP/ Boost sensor... all the way to the middle of the inlet manifold. Including the "T" pices. Most of the rubber was hard and brittle. Put good quality silicone hose in. I had already replaced the line from the input duct (Before turbo input) to the Boost solinoid.

Unfortunalty.. It hasn't changed anything... After a test drive around the block.. Boost level is fine.. But boost solinoid keeps "ticking" on off, on off, etc...

Any ideas? Maybe replace "main" relay or ECU? They are the only 2 things that control it.
