Did this a couple days ago.
Bought a package of 3/16" vacuum T's from the auto parts store.
2 in a package , look like X's
Removed all vacuum line from between the comp.housing and wastegate , including the restrictors and T-input for the solenoid
Cut one of the hoses in 2 pieces and attach all the X's
Reinstall between wastegate housing and compressor housing.
DO NOT reattach the solenoid line...............block it off.
You should be able to spike to 18 psi and it will level off at 16 psi above 5000 rpm.
cheapest boost mod I've found so far
My only concern is how much richer the car will run , but it should just be like using an MBC
I also haven't noticed any difference in idle vacuum( I have an Autometer PSI boost guage, instead of the factory BAR guage)
Lemme know your thoughts on this............
