hello guys. Is there any chance the position of the bov to confuse the airflow from the car? does it has any difference if the bov installed in the stm short route uicp (see tial flange) or like the oem location?

 

Did you install it back in correct position? It is possible to install backwards. Post some pictures for us to check.

 

i put it like the stm upper intercooler pipe kit. the Tial QRJ but it flutters or surges and i was wondering if it might be installed on the oem location near the intake

 

Fluttering is nornal. OEM DV works best but can't hold the higher boosts. You will need to tinker with setting to where it is tolerable.
