I have a Stratified single file 93 and E30 combo tune with all 5 slots used. 93, E30, 93 eco, E30 eco and valet mode. I have Stratifed traction control on by default. My question is whether the Stratifed tune overrules the OEM traction control, the OEM stability (yaw) control, and the OEM torque vectoring. If not, does the OEM off button still work and does it maintain its 2 step function? If it does still work, what does it do? And does torque vectoring always stay on regardless of the use of the button, as it does when stock? See pages 12 and 13 of the FiST Supplemental Owners Manual for a full description of the stock setup. Thanks.
