Default help! (super noob) bad idle and misfire changed CAS

My car was boosting and was running fine but the idle kept going up and down and after a rev it would stumbled all the way down, sometimes it would barely catch itself and sometimes it would die.

other than the idle issue the car was running good until all of the sudden when putting a little bit of foot into the throttle it would start missing right before boost (once in boost it was fine)

Another day came and the car was backfiring and missing very bad with any amount of throttle I put into it. I took the car to my buddies house to plug in my megasquirt to the computer to see if there was anything we could do with the tuning because the car is running very rich ( around 11's to 10's anywhere from idle to boost) I was messing around with the computer and got the idle to smooth out a little somehow(noob). but the idle is now around 200 rpms and I cant seem to increase it.

after searching and searching all day I decided that I need to change my CAS. I took the one off of my old motor and switched them out but there was absolutely no difference and the car is still running really rich.

I have no idea what it could be and after a lot of forums I still cant find what it could be please help!! or direct me to the correct forum if there is one!

You didn't tell us one single thing about your car or the turbo set up. Nothing.
