Cant get rid of whinning
 

I installed a throttle body spacer a few weeks ago and it whines really loud starting about 1800 rpms. My budys have them on there trucks but they have silverados and they dont whine... Was wondering if anybody else has this problem? I went back and double checked for leaks and cant find anything? Is the throttle body spacer even worth keeping on the truck?

Read many times that throttle body spacers dont do a thing unless you spray.

i have heard that and also heard that it is supose to really help gas milage?
Just trying to decide if its worth dealing with the whining or just take it off

i cant see how that thing is going to help gas mileage lol its just a spacer.
