I must be lucky because I bought my truck used last July. It's at the dealership right now for EGR and head gaskets. I was very up front with the service rep, told him I believe the previous owner had a tuner on it but I bought this from another dealership and they said that the remaining warranty stands.
I spoke with the rep today and they said that my computer did in fact show a tuner and that they would put it back to stock. They are also going to allow me to upgrade to the studs and further told me that there head diesel mechanic does complete EGR deletes that he makes and installs once my warranty is over with.
