    Limit the valves to 20 degrees or they will attempt to advance and retard passed the limiters.
    You also want to change your exhaust overlap border.

    Take them out your low end torqe gone. we make 426hp with intake and full exhaust the cams say 417 you will loose almost 100lbs torque until 5000 rpm
    boss cams c.a.i, full exhaust go with cobrajet intake if you don't want boost the boss isn't worth the $

    I too am having issues with new cams. Car will start and die. It is having trouble idling. Drives great but can?t keep idling correct. I have adjusted fuel trims and torque tables. Any ideas anyone?

    Your torque tables need adjusted and the inverse table must be rescaled and recalculated.
    No files were posted. The problem could be something you changed yourselves. Future reference. Post the problematic tune file and datalog..
