i know this has been brought up before but i couldn't find it except for one post about belts. I just installed a 2.93 pully with the predator flash tune. runs great but what is up with that constant whistle or whine? not to bad at idle, just gets lounder with higher rpm, its not even in boost. i saw someone saying that the gatorback produces this whistleing sound, which i just put on with the new pully. it is coming around the belts, so it may not be the blower. i'm just lost and want to make sure its not a problem.
