I tuned this car about 2 months ago. Cars been running great without issues till one day....it just dies.
Restart the car, drives fine for 2 weeks. One day while out driving...dies.
Fast forward, now the car won't stay running at all.
Starts up without issues, it's set to idle on the high side due to the large cam (and this thing likes a LOT of air) and it just dies after a few seconds. If I keep my foot on the throttle it will stay running, as soon as I let off...it dies.

I'm open to any opinions as I've tried everything I could think of to get it to run. Even swapped the TB to stock to see if anything changes (it doesn't).
Doesn't seem to be the VATS system. Ruled that one out. Car is low mileage, 16,800 miles. 400 miles on build.

It almost seems to me to be when it transitions from cranking to idle, is when it dies.
