Greetings, hope you all doing great. So i have good experience in gm tuning and tuning in general never faced these silly issues before, so the car rev limiter on p/n wont pass 4000 rpm although i did what i usually do on any gm and works fine until 2018 , and the speed limiter seems to not getting disabled, attached is my tune , i have some ideas about how i may fix it but rather not test it on clients car so any suggestions
