High boost numbers- Low power- Funny Noise Help

shmoozer · Mar 2, 2015

Alright friends of PSA, I've got a couple questions. Hopped in my truck this morning to let it warm up before heading out to run some errands. Driving down the hwy I notice that my boost levels were awful high for the speed I was going. I let off the pedal and it sounds like a BOV. I've heard this from 6 liters before but never this loud. Took the video below to illustrate what I'm talking about.
Truck is an 04 with 144,xxx miles stock aside from a 4" turbo back exhaust and an Atlas 40 tune in the FICM.
Any thoughts or help would be greatly appreciated guys.

Have the veins in the turbo ever been cleaned?

If not I would start there.

I don't believe they have, and that's kind of what I was thinking was going to happen

I just had this problem a few weeks ago, I Picked up a VGT pigtail off of Ebay for $14 wired it up and problem solved. Not saying this is what is wrong with yours but a $14 starting point isn't bad to troubleshoot it before having the turbo torn apart. Although having the turbo cleaned is never a bad idea..
