6.1 Swap Won't Rev Past 3K HELLLLPPPPP!!!

You gotta tell us all the info. So you got a different pcm, 5.7 hemi standard trans, and the guys over on DSP told ya that the predator you had was wrong and you needed the u7137, and have you updated the predator as they said? Just a thought, but have you changed the knock sensor? I'm no guru, but thought I would ask. Let us know if the new download helped from Diablo.
