I took mine of a while back its supposed to give you a little more turbo whistle is what they say. Some say quicker spool up. Its real easy just plug the hole in the intake with a 2 1/2 quick plug i got one from home depot.
I would say i maybe got some more whistle, but for $3 its worth a try.

I have mine off. Just plug the hole and your fine. It doesn't need to be on the truck.

Be sure to check the plug every other month and lube it with vasoline or something, I have heard horror stories of the rubber in the plug dry-rotting and coming apart and allowing pieces to enter the turbo.

I put a cap on mine. Less likely to get something dropping in.
