How do I go about calibrating my TPS on a Gems Controller, Do I need to send it back to MPI to do this?

Sled has low idle problem, TPS reading with controller installed is
D01 (17-85) are my readings. I have to check what stock reads. Idle will float around 900 rpm to 1800 rpm and sometime stall. Smells ritch.

Seeing what my options are with this and if anyone's had this issue with A MPI 190 rear mount turbo and Gems programmer.
