Which shift does it occur in?
I know your order form said that there weren't any transmission modifications but are you sure? Could a previous owner have done something to it?
The tunes you have are very similar to all of the PMT1 tunes that Bill has put out for quite a few months (and it's the most-used 7.3L platform we sell). I have looked at the programs and can find nothing askew with them.
Which shift (1-2, 2-3, 3TCC apply, or 3-4)? I'm wondering if you are feeling the 3rd gear torque converter clutch apply at approximately 35 MPH. Your NVK2 didn't do that under normal driving.
