Come winter we will see if it rears its ugly head again.
And when did you have that Tune installed...

April 12th was the day I installed the tunes but I didn't have my switch in until April 23rd. Correlation or causation? What might you be implying?
Only thing I can think of is the turbo brake but in my testing it didn't seem as if the vanes were stuck so I am unsure.
