dude, learn to spell....


There's a short vacuum line right at the turbo; it runs from the intake side of the turbo to the wastegate actuator. Is your boost controller located in this line or did it get mounted on a different vacuum line?

Yeah, that's the vacuum line. So the controller is in the correct spot. My guess is either the solenoid for the ebc is broken/stuck closed, the setting is in the wrong place, or something isn't connected correctly. Until you figure it out, remove the boost controller from the vacuum line and just run it as stock. This way you should be boosting to safe levels and you won't risk damaging your turbo or your engine.

Also, look in the MKIII Supra FAQ and check for error codes. Reply back here once you find out what the code(s) stored are.

Nope, the purpose of the boost controller is to restrict and regulate the amount of boost pressure the wastegate actuator sees. If you had a "Y" connection, the wastegate actuator would see full boost and still open at the factory setting. Proper installation is to have the boost controller inline between the wastegate actuator and a boosted vacuum line.
