Exclamation 86.5 7mgte

I am having a boost problem. The car is bogging down while under 3psi. This is my First Turbo supra and im not understanding why it does this.. i do have a major exhaust leak by the second cat, and i might have one on the down pipe. Will this effect boost? when ever it spools it bogs down, my knock sensor code is up and also turbo pressure sigal?? what do i do to fix this problem

the turbo pressure signal = you have a boost leak which is causing the bog

also you will more than likely find that the wire has broken off the knock sensor plug or has a short circuit, or is not plugged in at all
there are two knock sensors on the intake side of the block about #2 cyl & #5 cyl
pull the plugs off and inspect them

good luck
