whats up...i am currently in permanent ttc because i am trying to figure out my boost problem. my boost will raise until around 9 or 10 psi, then drop to around 7 or 8 psi, then shoot up to around 17 or 18 psi. i cannot boost above this with the boost controller maxed out, or with the wastegate hose pulled. i used to be able to boost and hold whatever i wanted to, the boost would raise without the drop i am describing. what can be wrong? i am in ttc now but in ttc and sequential the boost does the same thing. ever since this problem my idle is a little messed up too. im hoping that it is a boost leak. any suggestions...thank you. also, there is no death whine or smoke of any kind.

First, make sure all of your intercooler pipes have good connections. ( A loose intercooler pipe can cause a rough idle and strange boost symtoms like you are seeing.)


Do you actually have you actuators "hard-wired" open? If not, you could have a flaky VSV or failing actuator.

If you DO have your actuators hard-wired and are still having this problem, then one of your turbos is probably going bad.

Hopefully it's just you intercooler pipes!
Good Luck,
