hey all. really new to tuning. ive been reading and watching many videos though. im currently just running my 2019 LD silverado 6l80 with dod turned off and TCC unlocked 1-3rd. today messing around i adjusted my tire size on HPT to my proper size and looking at everything that it automatically calibrated. i noticed that in my pattern A ,tow haul that it has my TCC apply in 2nd and 3rd both set to the same speed. stock they were offset by 1 MPH. why would this be and will it cause me any issues
i also noticed that it messed with my 318 MPH lock up speed and unlock speed of 317 for 1-3. it changed the unlock to 318 so i ended up with 318 on both lock and unlock. slightly scared of what else it may have messed with that im not noticing.
thanks in advanced
