Wine could coming from the transfer case. Checked that out lately?

Might be a given, but did you disconnect the battery after replacing the solenoids and installing all those parts?
What did you set your base fuel pressure at (with vacuum disconnected)?

I dint really set it it seemed set but it deffiently smells rich I didnt really understand how to set it right?

I just went and adjusted it at 44 with the vaccum disconnected its running 41 with it connected should i make it higher

Boost leak test? Could be a simple vacuum leak somewhere.

whats a good cheap way to test soap and water seems to evaporate too quick how about seafoam?

Soapy water is the best way. You're using a compressor to pressurize the system right? Can you hear any leaks/does pressure hold on your gauge (boost gauge or on the tester)?

As for the fuel pressure that's normal, once vacuum is connected it will drop a little.
