just put the car back to stock (intake piping, cat, intercooler, thats it). After takin it for a test drive, the car will have the vaccum pressure, but when i step on the gas and it starts to boost, once it hit the psi part of the boost gauge, it bogs hard like i hit a wall. It wont allow me to go any further, I just have to change gears and go back to the vaccum pressure.

Then when I stop the rpms drop and the car will almost die, but it catches itself and stays running.

only leak i think i make have is that one weird shaped connector that goes from the bottom of the intake box to the side fender. Everything else is AOK.

Any ideas?
 
rookie here,

why would this cause it to bog. do the injectors continue to inject as if there is boost, causing it to run to rich?

Are you using stock injectors??? AFC?? Sounds like fuelcut.
