when the truck was idling i was hearing this funny tinging kind of sound. so i started to cover up the wastegate dump and it was sucking air in? is it suppose to do that? and when i covered it ( not completly ) the sound went away so i figured it was caused from the air being drawn in... sorry this was baffling me all day...

 

my wastegate has never done that. im pretty sure its not suppose to it almost sounds like it got stuck open. what brand is it. i could be wrong but i never heard of that.

 

its sts...what do i do if its stuck open, play with it or get a new one?

 

are you talking about the exhaust dump part of the wastegate that is sucking in air or the little tube on the side ive never seen the sts one. i run a tial.

 

the dump...i dont know all i know is its an sts kit i bought used. the hose part has a hose on it for the boost controller but the boost controller isnt wired in yet

 

IIRC, the STS comes with a Tial.

The WG should be shut at idle, so you shouldn't feel anything coming in or out.

 

hmm so whats my next step?

 

Get a new one.

 

Pretty sure he's talking about the blow off valve. Sound like you have it on a stock motor and has more vacuum then the other setup. You probable need a stiffer spring in it or adjusted (tightened) if it's adjustable

 

ive had the kit a week!...how come im not losing boost or anything...im still hittin 5psi?
