    working on 6.4 with hellcat blower tune

    So i have been working on tune, for the most part its running pretty good, when i did the engine tune on car the trans definatly got too firm for normal driving, its hitting pretty hard in 1.2.3 up and downshifts, i am not sure why the trans is doing that when i havnt touched it in the tune, its not terrible and i drive it every day but i would like to fix that, Also i noticed on a pull sometimes if i hit the rev limiter it will go into some limp mode, turn car off runs fine again, its been a battle getting this thing running right, normal drivability is just ok would like it to be a little smoother . i do know tuning with the smooth boost on these setups is annoying cause you dont get boost unless you hit wot, that part the car runs great

    yea why is trans shifting harder in the tune, what things in the engine tune would have done that. and best way to smooth out the shifts now

    also why would it be going into limp mode hitting rev limiter

    No data log and tune file posted, this is what I'm working with.

    How can anyone give you any kind of advice without both a tune file and a data log? Do some reading on here, cowboy. Without both, you're literally guessing. Might as well be using a crystal ball.
