Update.
Since getting it back it has not been 100%. It ran great 95% of the time, but at higher rpm, it would kind of fall on its face and slowly stumble out of it. Only really came into play when severe lead foot syndrome was involved. I only put maybe a couple thousand miles on her a year now, and did not get around to getting it in to get looked at.
Finally got it to Randy's again and they had the issue figured out in short order. With the turbo wound up, it was sucking the intake tube coming from the filter flat. It was still the factory original with a K&N filter in it. Filter was clean. The added ponies from the SCT programmer probably contributed too, but age and filter oil causing degradation were probably the bigger factor. They put an S&B cold air intake in. Back to "you better be holding" on status.
Glad to see Randy's still going strong. When ownership changes on a business, you wonder how it is going to go. It's been 3 years now. Haven't skipped a beat from what I can see. I have been going to them since 2001, when I got this truck Shout out to them.
