    HELLCAT TB on cammed 5.7

    Hi everyone, I am looking for some help with my car. I am installing a Hellcat TB and have seen conflicting information on what throttle tables to adjust and by how much. I have also seen many posts on these forums that are not convincing on the best way to go about this. Currently I have 3 Throttle tables in my 2012 Challenger. One theory suggests to multiply my existing throttle airflow table by 1.15. Others have suggested to multiply the table from .5V and up by .7 to remove 30 percent???

    Also, which of the three tables controls throttle sensitivity???

    Looking for help, thanks in advanced. Screenshot attachedHELLCAT TB.png

    I'm in the same boat as you. From what I've gathered, the 3 tables work together. Sensitivity is controlled by setting the voltage in the rpm range to 3.80(3.79) from 1k-6k, it should allow you to open the throttle blades a bit sooner. I'm still investigating this so take it with a grain of salt. I have lots of issues to work through in my tune.
