ok thanks guys. I am tryin to narrow things down , I still can't find this leak it's drivin me nutsss.
I sounds like you may have lost the ECU wastegate control. Check your wire going to the waste gate solenoid.ok it's only peaking to 16 psi then it will drop to 9 really quick,Then it will slowly start to climb back up to about 11 12 and that's it all it will hold .
alll this starts at about 3k in 3rd then by 3100rpm i am down to the 9psi and it is constantly building and droping i just dont kno ?
