Codes P1516 and P2101

I was in the middle of a ECM/TCM tuning session session when it began to throw these ECM codes, which cannot be cleared no matter what we try. As soon as I put it in Drive - boom - codes everywhere.

They indicate TB issues so I'll send it back to NW, but I'm not convinced it's a TB issue such as bad electronics.

Anyone experienced this?

A while back I had a similar issue... there was a throttle body code that would pop up randomly onces I changed to a Katech tb. I cleaned the contacts and applied dielectric grease,never saw the code again.

I would go and look in the HPTuners forum for those codes and see what they say.
