VGT issues
Like it say I had a VGT issue.
I don’t drive the truck much and the turbo was stuck , and stuck bad . Truck is a 2003 with 227,000 on it and this is probably the fourth time I’ve cleaned it . Truck also has all the mods that make her live .
Ive had a hyper tech tuner and I used to just keep a tow tune in it . In November I took it out out her back to stock . Around Christmas I noticed the turbo getting worse and then totally stuck . Thursday I took it off and it was really gummed up and rusty again , unison ring was stuck on really well . So I clean her up got it back on yesterday and took her for a spin .
well just like it was stuck the vgt not working.
brought her back and checked for codes and none . So I was thinking the actuator was bad but no code for it .
so I decided to put the economy tune in just to see what would happen. Well all works perfect now turbo spoils fast as hell .
I just don’t understand why it didn’t work with the stock tune in it .
many ideas y’all?

I don’t know about the tuning but...If you want to clean that turbo for the last time do a CCV reroute and you won’t be sucking oil vapor into the turbo. It’s the best thing I ever did to my truck for the health of the turbo and intake system.
Not being rude, just letting you know a turbo does not “spoil up” it “spools up”. I see that post here a lot.

You have one of my fav turbos (03-4) and I'd invest in a GT3782VA rebuild kit with new (brass) thrust, journal bearings, VGT solenoid orings, wheel/shaft, snap rings, seals, etc. Stick with Garrett/Honeywell parts --- kits are around $200.
Cleaning is only part of the problem with that mileage.

I have 270k miles on my Excursion! Turbo stuck and after getting tired of repairing and replacing....I bought a new Turbo and learned I separated the inter cooler after all the work! You aren't the only one with this issue!
