Ok so I finally have a big Whipple throttle body Hellcat that is going into REP Code u1424. I know someone knows there is a table to adjust I just haven't found it yet. Car starts and drives awesome but will eventually go into REP and show this code. IF anyone has any tips I would appreciate it. I have asked a few people but no one is willing to share. Sucks but I understand. Ill eventually figure it out just trying to save some time. Thanks guys.
