Protects the turbos by dumping boost when you shift (i.e. when you let go of the accelerator).

On the Mkiv Supra TT it's located above the front turbo, near the rhs cam/valve cover.

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.
