hey guys,


so this is what my problem is: anytime i hit ~20lb + boost there is a really weird noise that comes up, this is my current setup and ill attach a vid link.

Cobb intake
Cobb inlet
Cobb UNCP
Cobb LICP
AMS Front Mount
AMS Wide mouth downpipe
MAP test Pipe
Stock catback
AEM boost gauge
AEM wideband

I was doing a pull in 5th gear, WOT at 3k and reved to 5.5k rpm

is it that wierd high pitch screech?? or what is it specifically?

 

yea that high pitch screen, i cant figure it out.

 

My evo 8 did that too, even when I changed turbos. It had an HKS filter on it and I think the metal around the filter element caused it to "whistle/screech"
