i have a 2019 challenger rt with the 8 speed that has everything in my bio down below done to it. i am looking for people who have tuned their 5.7s after similar mods to try and get a shift issue fixed. i have been trying to get my 1-2 wot shift down but so far nothing has worked. i think i have a bad convertor or missing 1st gear teeth, but i would like to try and save $3k+ if its just a stupid mistake thats been over looked
