hey,

about 3 weeks ago i did the 6637 intake. since then i began hearing what i think is the wastegate relieving pressure whenever the truck shifts or if i let off the pedal. actually, as you know, this sounds pretty cool and i like it.

this morning, when i left for work i had to pass a truck a couple miles down the road. this pass needed no more than 3/4 pedal. when the truck shifted back into o/d, i heard the wastegate functioning but i also heard a really weird sound with it. hard to explain. almost like a screech sound...or the sound of two parts briefly rubbing together. this ONLY occurs when the wastegate is relieving pressure which ofcourse is just a brief moment.

now whenever the truck shifts (at rpm's high enough to have the wastegate function) i hear that sound.

the turbo itself sounds fine. no drivability problems. only the sound i described seems wrong.

again...its like a screech sound only when the wastegate is functioning. kinda reminds me of some kind of plastic on plastic sound. i haven't had a chance to pop the hood yet...i just got to work.

any thoughts??

thanks in advance
