BAMA Ghost Cam Tune, GOOD OR BAD?

[Jeremyd43]

So i recently put the ghost cam tune on my car and i am curious if this has any negative effect on the engine? Of course the BAMA guys said that it doesnt but i have noticed a few things that have me concerned. One thing is that it will occasionally die at idle because it causes the rpm's to go so low to get that lope sound. I have also noticed that sometimes it doesnt make any type of "cam" sound and then i give it a rev and then it will kick in. Finally i have heard on a couple ocassions a kind of knocking sound, i think this is because it almost acts like it wants to stall out at idle. Just not sure if faking it just to get the sound i want is worth it. Maybe there is something i need to do to adjust for this but i dont know what that is.
