Faulty install or fault EBC, solenoid etc?
Car has AAM TT system.

It kinda sounds like you may have the vacuum line on the upper port on one of your wastegates instead of the lower port could be a simple oversight ....I have the tial wastegates and there are several ports on the upper part and a upper side port can easily be mistaken for a lower port ...I did that myself ......late night car modding after few too many beers lol
