When I did this to my 1G it raised the boost to 15psi. I think it depends on the car. A friend of mine did the same thing and he was running 12psi. I would recommend getting a boost gauge before doing it. Hope that helps out some.

thanx man i was just wondering who else has done this..heres what my conclusion is..ok im pretty sure its opening the wastegate early to allow my turbo to spool more air in..is this wrong or does anyone else know what its doing by unhooking these 2 lines..thanx again for your replys

From my understanding, the BCS regulates the amnt of air that is going to the turbo along w/ the MAS. You could get a couple more psi out of it, but it might screw w/ the ECU by not reading the pressure correctly.
Im not too sure about 1G though....
