i installed the cai 91 tune
throttle boost 20%
firm shift points
and adjusted the neutral rev limiter up a bit
then after loading the tune i started my car and its idling real rough and the check engine light is on. i tried to drive it but runs like shit. i then tried to restore original settings and keep getting an error trying to restore. something about the shift points and shift firmness not being able to calibrate. i also tried force restore and it gave me a code with a bunch of numbers and letters that doesn't work either. what do I do?
car is a 05 dodge magnum 5.7 hemi

This may sound like a dumb question, but did you run your tank down to near empty, and then fill up with some 91 octane BEFORE you installed the tune?

clear codes or pull the battery for a minute...

A friend had me pull the #11 or #12 fuse for a minute and that solved the problem. Runs like a champ now.

I'm having the same problem. rough idle and no power, I just did the CAI. And when I try to reset pack to my orignal program, the intune reads "no ECM detected". Did you fix your problem by by unplugging the battery or pulling the fuses?
