I just found a thread in Corvette Forum where a guy claimed he could eliminate the TPMS. I did a bit research and apparently he could reprogram any GM control module. This opens up possibility eliminating the DRL (Z06), the auto headlight (Silverado, Z06, and Kappa), and TPMS (Z06 and Kappa).
Maybe he can reprogram the HVAC control module to eliminate the automated function such as AC compressor must be engaged and the air cannot be recirculated when using defrost function. Maybe the TC/AH can have a default mode "completely OFF". And, maybe, the low beam on the Silverado can be turned on along with high beam. Heck, I'll have the fog light on all cars to stay on with high beam.
