Y'all reckon my 6.0 got screwed up?

Here's the background (also see sig for specs):
Intermittent turbo overboosting, lack of power when it wasn't boosting properly. I told them it had been doing this for a couple weeks but I just watched my gauges and didn't lay in the throttle after seeing it boost over 35psi. Been able to drive it with light loads as long as I used the gauges. I figured sticky vanes or a crapped out VGT actuator. Didn't have time for DIY so took it in to the dealer get it looked at. (134,000 on the clock)

Relayed the above information, also stated there was a tune installed (no warranty to void) and that if he needed it returned back to stock to let me know and I would. Get a call the next day that on the test drive it boosted "over 50psi" and then puked coolant. They were getting ready to pull the turbo, clean it and replace the vgt actuator as soon as it comes in today. They mentioned they were worried about the heads now...

My main question is do you think a knucklehead ramping the boost up to 50psi for a short period would stretch my ARP's?

I am having them go ahead with cleaning the turbo, replace the vgt actuator and I may go ahead and pick up a new degas bottle cap to see if that's the puking issue. They also told me they went ahead and returned it to stock after I told them to let me do it b/c I had a tuner. I guess I'll be sending my SCT back to get it unlocked now too...

I do believe the knucklehead ramping it up to 50psi of boost definitely caused whatever made it puke coolant. I don't think it would've stretched the ARPs though, I mean thats what they meant to prevent. I think you're right on track with buying a new degas bottle cap and hoping thats the issue. But if its not, I think you know where to look next

Sorry to say, but you should have returned it to stock before you dropped it off. Good luck with your truck and hopefully you get everything figured out.

No doubt I should have done that, I don't mind taking the SCT unlocking $ on the chin. I specifically said no re-flashing but shoulda known there's no control over that. My main concern is my ARP's/heads right now.

dxusmc I hope your right!

Mine puked about 1000 miles after I got my studs put in. Replaced the cap and all has been golden ever since.
