anyone had this after egr delete?

So i finally blocked off the egr cooler (couldnt afford to delete it right now)..truck seems have better throttle response and everything but.... after ive driven a few miles i hear a sound like air blowing when i get in the throttle (didn;t happen before delete)...im assuming this has sometihng to do with the turbo..it only happens for a few miles then everythings back to normal. Should i be worried about this or has anyone else had this happen. I've made sure everything was back on good and tightend. The boost pressure also doesn't go up at high anymore..is this common too?

any info on this would be great...
thanks

So i've been messin around with it for a few days now and heres what i've figured out....maybe someone might have an idea about this....

- noise only happens when truck is warmed up after a few miles...then just goes away after a few more miles.

- if i've been driving for awhile and the noise is gone...i can turn the truck off then right back on...the noise comes back for a few miles...the goes away again...


I would think if something were broke, cracked, or not on correctly it would make the noise all the time..but it doesn't....im gonna put an sct tune on it this week..so maybe that will help...but if anyone has any idea help me out....

If it's the up-pipe you should start to see soot covering something (cab,bell housing,etc.)

I went and checked again...it kinda looks like there might be some soot right near where the up-pipe goes into the engine...i blocked that off though...if the v-clamp isn't all the way tight and its blocked off could that soot be comming from the intake side?

sorry to keep posting...just trying to figure this out

If you dont have a tune that keeps the valve shut, I think that is the noise you are hearing. When I blocked off my uppipe and then took the SCT out, my truck made funny noise like that.
