After the tune was flashed into the computer, The car started and ran, but the anti theft light was on. I drove it a couple of miles, shut it off, and restarted it because it wasn't making any boost. Once I started it, the CEL was on. I drove it back home, shut it off and checked the DTC's. The only one I got was for the MAF airflow not being correct. I checked the MAF connection, and it was good. I cleared the DTC's, turned the key off and then tried to start the car. I would crank and start but just as soon as it started to idle down, it would die. I've double checked the tune to make sure I didn't overlook anything. I could get it to run if I feathered the throttle, but it absolutely won't idle. I took a log of it running while I was feathering the throttle and I took a picture of the last DTC screen that I read. Any help would be greatly appreciated.
