Low Boost Problem

[BoostedK20]

How could it be backwoards?
I've a "Y" connector at the end of my intake manifold with one line which goes to bov an the other to the wg (44MVR). The one at the wg is installed at side, other sideports are closed and the upper for boostsolenoid are open.

As a start, you should never Tee your wastegate and BOV. They should have their own vacuum sources.

check and see if the solenoid is hooked up this way.

Follow this diagram when you have a boost controller

Wastegate is a 44mm MVR.
Now I've welded my dumptube that it's open because I thought there could be too much backpressure between downpipe and wastegate but still boost creep. After that I made a port in the compressor housing for my wg with a shorter line but still boost creep.

Here's a pic of my manifold. I know the position of the wg neck is not the best...

Definitely a creep-able manifold. Seems that this isn't the issue though. Just because it looks like it can creep doesn't mean that's why. Ensure that the vac line isn't kinked and is big enough and strong enough. There are many cases where poor vacuum lines end up collapsing, typically when things are hot. Also, as a rule of thumb, make sure to zip-tie your vacuum line connections. Slip-fit barb fittings alone don't cut it.
