So my JWT/Pop charger and z tube came in today and me and a buddy installed it. Cant complain love the engine growl + a lil hp but what im concern is when im driving rev'ing it up i can hear like a whistle coming from the pop charger is that normal to any of you members who have pop chargers installed on yours? your help would be greatful thanks!

 

The whistle is normal.

 

kinda stupid but it almost sounds like a lil turbO ><

 

yea its normal, but you'll get use to it after a while.

 

Its normal

Do you guys get the whistle mostly between 2-3k rpms?
