There is also a vaccum hose connecting the intake plenum with the throttle, do you have any idea what it does Cant find if there is a crack on it. I will get some Samco Vaccum hose and replaced as may as I can. This might help.
The best way to check for boost leaks is to pressurize your entire charge-air system with an air compressor (up to about 30 or 40psi - if it can handle 40psi cold, then 20psi or so hot should be no problem). With 40psi of air in your charge-air system, you should be able to hear any/all boost leaks loud and clear.

Displacement is no replacement for boost.
Life begins at 30psi.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
