Finished installing a 2000 5.3l in my 69 camaro. Just got my EFI Live software today, got everything hooked up and working.

I disabled the VATS and flashed the PCM. The engine starts but won't stay running, is there something else I need to do?

I enabled the scan tool and selected the PID for the below, the data results say that it's enabled. I read back the tune I flashed from the PCM and it had the VATS disabled.
