I would guess you are correct. id kind of like to know their methodology as they remove torque safeties and then add boost and timing.I think most tuning is done from OTS files. You just use the files based on your Mod variables. From what I’ve seen for tuning the GR Supra is that a lot is based on removing torque blocking guard bands put on by the factory. That and every tuner adds their own little spice to Fuel and Timing maps.
