Status update
Since I have disconnected my IACV I have had no problems starting the car! I've been running autotune and its running great. I do keep loosing communication with the MS just long enough to give me a message to select which tune I want. I just select the ecu one and move on, i'll look into this being a loose connection with the serial port or if I am still getting a short some where.
