so yesterday i tried to install a manual boost controller and when i pulled the hose that comes from the wastegate the 3 way plastic that connect to my intake manifold and fuel pressure regulator broke.

so, i bought another 3 way plastic to reconect, but then this time when i floor it in first gear it goes up to 15lbs and down really fast to 8.5. when accelarated in 2,3,4,5,6 gear it goes up to 13 and goes back really fast to 8.5

i installed the boost controller before the 3 way conector and it still pushing the same lbs as stated above.
