Subaru Banner AVCR problem

I installed a Used AVCR about two weeks ago. Car pulls great but I am getting a werid sound from under the hood at .85 and above. It is a high pitched ? ? Doubled checked the conections everything seem fine. But I can not figure it out.
Mods are; Turbosmart BOV, catless back to Blitz Nur spec


Thanx for any and all input

Did your recirculate the NC port back into intake? If not, you’re likely hearing the solenoid dumping wastegate pressure to atmosphere while the wastegate opens. Either that or the pressure sensor might be making a little noise. Check to make sure the plastic housing doesn’t have a crack or something.

A few helpful links:

http://www.clubwrx.net/forums/showth...highlight=avcr

http://www.plxdevices.com/ECUDatabas...SUB_WRX_04.pdf
http://www.apexi-usa.com/pdfInstallation/21.pdf

PS: If you think you don’t have it wired correctly you wouldn’t even be able to tune it. Is it correctly learning the wastegate duty cycle automatically for each gear? If not, then you may have mis-wired something or have the settings way off. Pay special attention to the clubwrx link above…

~Good luck..
