Interesting 'Tick' Noise from engine

[mborg1]

ok heres the scoop of why it ticks...the regulator is designed for certain amount of pressure coming from the wastegate..when you installed the MBC it allowed more air to come in, so the sensor wants to limit the air.. try this, close the MBC so that its back to normal...it should go away..so when your adjusting your boost, just listen to that and if it goes away then your where that sensor wants you to be...( thats from the guys here in N.Cal who works on STIs all day long)..but from my friend Arunto you can get something to control that....its here in the forum where he got it...but correct me if you think im wrong..
