Possible boost leak?
So driving over the pass last weekend, I noticed as I reached about 15 psi on my boost gauge the needle started to stumble/flicker and I could audibly hear a "pffsssfftst" at that same time, back down away from 15lbs boost and the noise goes away? I am leaning towards a boost leak, it sounded like it was coming from the driver side anyways. I hate to just assume it is something, and mindlessly throw parts at it, on the other hand I know that is one way to start replacing old worn out parts.... So I am thinking start at ordering some new CAC boots from riffraff, anything else I could consider? Could be a worn out spring on the wastgate? Thanks

I never noticed loosing boost but I could hear a whistling noise on my 6.0l and it turned out to be a crack in the feed tube coming up to the turbo on the drivers side. Seems to be a typical issue after enough miles especially if the pipes have been removed for other work.
I was somewhat pissed I wasn't told to replace them when I had the motor bullet proofed.

Copy that, I will double check when I get home. I do recall there being a little bit of dirt/sootiness around a few of the boots so maybe its that easy, would not be bad to replace them like you say.

I don't see his sig on my crappy computer haha. I'm betting it's surge then. My f250 had it till I changed to the wicked wheel, prolly a better option now huh?

I clicked reply right after he posted, walked away while typing my questions, then came back later and finished my post. When I clicked post and saw you had posted during my delayed response, I saw you thought the same thing.

Not familiar with turbo surge, and yes the Chip was installed by the PO, 6 position TS as far as I can tell, I would like to send it out to gearhead to have it reburned.

Mine was not that bad, it was fairly intermittent right at 15lbs of boost, it sounded exactly like the first video starting at 1:38-1:47 - I never heard that other high pitched fluttering like they had? When I backed off and went easier it went away, so maybe it was a little turbo surge but nothing as bad as they were experiencing.
Shoot, now listening to it again after 1:48 it might have been doing a little fluttering like that end part... Sorry it was a 10 hour day of flights, with a 3 & 5 yr old kid, then driving home at 9:00 at night for 3 hours so it was a long day...
