i know this is a old question is some other thread, frankly i didnt feel like spending 45 minutes using the search feature to find some small thread in which id prolly never find the real answer

maybe you gyys could shed some light on my problem, i have a 2005 tc, trd supercharger, nst 9.5 lbs pulley, weapon r intake, the car was in storage over the winter, i did start it but a few times, it had some bad gas in it so it took me while to clean the butterfly on the throttle body, but once i started it and took it out of storage about a week ago, the supercharged has a very loud whine, i know i know its supposed to have a loud whine sound, but when i first installed it it was actually louder at idle then between 3 and 5,000 rpms, now its just really loud all the time, the BOV or boost "bypass" valve you can hear it but not as much, idk what to do......

edit

boost gauge says its at 4 lbs, the nst is 9.5 LBS pulley but its a vac gauge and not a press gauge, i know ill lost some psi due to bigger exhaust (header, downpipe,midpipe, drift spec exhaust), i have a full system and the weapon r intake has a bigger diameter pipe on it versus the supplies trd black airbox, car isnt throwing any codes either......
