Guest George89 Posted June 3, 2012 Share Posted June 3, 2012 My 2nd turbo won't kick in it just makes a loud noise when its ment to kick in. i have checked everything and i am going mad! until i figure it out. i done a boost leak test i found few leaks, i fixed them but still not fixed. I realised today that the 2nd turbo actuator rod is not completly closed is slightly open. Would that cause the 2nd turbo to not spool properly?

Guest George89 Posted June 3, 2012 Share Posted June 3, 2012 http://www.mkivsupra.net/vbb/showthread.php?27904-Sequential-turbo-problems&highlight=sequential I have read all that but i still don't know if it will effect the 2nd turbo if it doesn't shut. i believe its called the exhaust bypass valve Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted June 3, 2012 Share Posted June 3, 2012 Best thing to do, put the car in TTC mode and see if the performance improves. Quote Link to comment Share on other sites More sharing options...
