Hey everyone.
I have a lancer GSR engine in a lancer gli.I have a aftermarket boost control on it. BUT it does nothing as there is still anoriginal valve or controller or somethin stopping me from boosting over 7 PSI.
Does anyone know how to bypass this?? It would help greatly
thankz

 

You should have a line from the intake into your boost control then out to the wastegate actuator. Don't reuse any stock lines, just run new ones yourself. If that doesn't help, you have other issues.
