Unhappy 07 sti over boost

so i figured out that the car was in a fail safe mode when the barometric sensor wasnt plugged in, and i would not hit targeted boost. NOW with it in, I over boost and i overboost badly. The car is an 07 sti, the codes are not deleted but with the sensor plugged in there arent any codes. my question is on the valve unit, do you have to block off or plug anything? or just leave the valve ports exposed? other than the airpump idk what could be causing my over boost issue. ive replaced my bcs and my pill already

You should check the diameter of the hole in the pill.
The pill, and the diameter of the hole in it, are specific to the VF43. Make sure the vacuum line you got with the pill is really meant for a VF43; if it's a pill for a VF39/VF48/TD04 then boost will definitely be off. This pill business can be tricky, unfortunately.
Also, double check your wastegate actuator with something like a Mityvac pressure/vacuum pump; it should push the exhaust turbine flapper door wide open at around 7~8 psi or so. If that's not the case, then something is wrong with the actuator itself or something is preventing the flapper door from opening properly.

So I realized the codes turned on and the car is always in a failsafe mode now. although I know i will need these codes to be deleted, and have the car tuned anyways (stage 2 tune), On my accessport, the baro pressure (psi) fluctuates between 11.89 psi up to 12.04 psi. I have the sensor cut out from the actual valve itself. i was curious if there was a certain way to cut it out or if my sensor is just bad in general. I heard that the baro sensor should read very close to 14.7 psi. thanks guys!
