Will there be an updated version of the tunes to take care of the cruise control issue that FCA is dealing with? Is this something that could even happen on a Diablosport tune, or are they entirely different from stock PCM programming?

I'm having this same issue. Seems to me that part of the tuner should let you set the rev limiter to +6,000, not +600. If I adjust these settings at all my car won't idle. I know there is no real need to adjust them, but I, personally, would like to remove this limiter.
