The BDX is the new tuner that you can go through the OBD port. I would put a charger on it. I always put my charger on before I tune just to make sure battery is fully charged. You might have to reset your BMS for the battery.
I think my truck rides great. I also live in the terrible state of New York where there are plenty of pot holes. I was actually shocked how great it rides and handles.
I have 20’s on my 2023 with stock Hancock tires and it rides great. I also have 17’s with AT tires for the winter and I think the 20’s ride just as good or better.
I swap between summer my stock wheel and winter wheels. The truck automatically picks up the sensors. Been doing this for 3 years now no problems. I have a 2023.
I put one in my 07 Silverado Classic. It has been in for 3 years now no problems. You don’t put anti slip fluid for the truetrac just straight diff fluid.
I switch between summer wheels and tires to winter wheels and tires and never had to program the TPMS. It just automatically picks up the new wheels and tires.
