So i got my hands on a 2018 mustang gt with the 10r80 on it, put a jlt intake ad tsp headers without cats, i tuned the intake and gave it a little extra timing, now i tried adding a little more rpm to see how it carried power past stock red line, but would get some transmission limiter and immediately after some communication error, so how are you guys making the 10r80 shift past 7100 rpm?
