Boost issue

[thedudeswrx]

So I just put in a new boost gauge on my 02 wrx wagon. There was one already in the car so just swapped lines. Took the car out afterwards and now the gauge is only reading 7 psi at most (was boosting a 14-15 before). Thought something happened to the gauge line so blocked it off at the t junction in the engine bay to disable the gauge and tried it out again. Still no boost. Now I am lost. So long story short boost abruptly went from 14-7 at best. Any ideas where to start. I am new to Subarus (long time bmw audi guy) and don't know where to start. Thanks in advance guys

Ok so after doing some research looks like I may be having a bcs issue. Anyone else have any other ideas.

Sounds like the BCS. Put the car in test mode and listen for the BCS to "click"

Sounds good time to do some searching on how to put it in test mode
