First startup issue...VATS?, or Mods
Fired up my build for the first time, but it wont stay running.

Not quite sure what the issue is. It will start right up, then die after a few seconds.
I was told VATS was disabled.
Stock LS1, stock ecu, Twin turbos, 3 bar MAP, 80 lb injectors.
I know I will need a tune, but thought I could at least start it up and move it around etc.
welcome any thoughts.
that said stock ecu mean stock tune? I got a baseline mail order tune before I started mine since I had a pretty long drive to get to a tuner.
