I solved the issue, they disconnected the oem TPS and replaced it with a custom motec one, circled in yellow on the picture. They canceled that and put back the oem sensor which is circled in red, and added a motec wire to it to let the ecu read it.
had another slight issue where my torque would engage even when cruising but that was just low Tyre pressure. The gtr is fully fixed now with no issues, thanks for all the help guys.
