alright so i put on some perrin intercooler hoses the other day and i think i have some issues, but im not sure. everything spools up fine and holds boost to peak, but the sound has changed. im not sure if something isnt fitted correctly, but everything is tight. the sound has changed from the whooshing sound (dp, up, silencer delete) to more of a high pitched whistle sound, and when i let off the gas it dies down to a lower whistle. its so distracting that i cant hear the turbo much nor can i hear the stock bpv blow. is this normal? any suggestions for what i might do if i pull it off? tia. -greg

 

check fitment, you didn't tighten something down cause I have perrin hoses and they did not whistle at me after installing them.
