Can someone help me figure out why my motor will not start with this tune? It is on an airboat. When I steal the same exact tuned computer off of a 2009 Chevy Silverado it fires and starts just fine. I did write entire to this 2009 Sierra and no start. Any thoughts will be greatly appreciated. There is a battery shut off switch which we use in between tries. I need this done by this weekend.

Sounds like you probably need to disable VATS. Go to the "OS" tab when you have the file open, then click VATS 1 and VATS 2 and set them both to disabled. After that, save the file and write entire and try it again.
Are you cranking the starter with your own key/switch/relay? If you are, set the Starter Checks to disabled before a write entire as well.
