Truckin Stuff

Hello all, I have a friends truck that is an 01 LB7. It's getting the overboost in a freeze frame but no light. It was the stock tune when this was happening. He was pulling on almost level ground at 60mph. It's data was 33.5psi boost, 74.5% load value, 203 deg coolant temp, mass air flow of 45.60 lbs/min, but the throttle position showed 0.0%. I'm thinking the throttle position sensor but it's not throwing any codes. Any help would be much appreciated.
