Weird boost issue... Help please.
Details: 2010. 6.4. 138k, dpf delete, mild SCT tuned, 5" down pipe back exhaust, S&B intake.
Installed all performance parts about 3 weeks ago. Put maybe 600 miles on the truck since then and had no issues or problems. On a return trip from a weekend getaway, I noticed I was "rolling less coal" than usual once I got back into town. Stomped the pedal a bit and saw what I thought was grey smoke. Drove it to the house and parked it. No puking coolant, no thrown codes, oil is good. Waited about 2 hours and walked out to pop the hood, area around the turbo was still super hot. Seemed hotter than normal. Checked around again for leaks, and noticed nothing.
Left it alone for the night, and googled myself into paranoia. Started it up the next day and put the pedal down again. Next to no smoke until the turbo was de-spooling. I figured maybe the boots to the turbo or inter cooler were blown off or cracked so I checked those out. Nothing there either. Again googled myself into paranoia for the night.
Today I placed my cellphone near the turbo to record and check for "rattling or metal on metal noise" and noticed nothing.
I've got next to zero register able boost while in park, and about half the boost I did have when I took it around the block earlier. To me, it sounds like air is bypassing the turbo somehow. I'm losing my mind.
So here I am, begging for help from the wise.
My turner turns off the egr and dpf. Dpf was deleted, I still haven't installed the block off plates for the egr. Can't think of anything I've missed.
Your help and knowledge is appreciated.
