Custom tune problem

Ok, put a custom tune on the stang, and now when I put the car in neutral (from 5th gear) at speeds over 50ish, the car shuts off. I can start it right back up no problems.

My question is, which settings do I need to change? Idle speed? Idle limit? Rev limits? New to tuning so sorry if this is a dumb question.

Yeah, that was my question. What part of the tune? I have an SCT custom tuner. I can change lots of things.

After doing some research, I have found some people talking about some kind of safety "thing" that will shut the car off when car is coasting in neutral.

Anyone else hear of that?

Update*

Idle speed neutral was the problem!

Bumped it up from 720 (default) to 840 and it's fixed!

I had a nightmare of a problem when I first got my sct... It made my car not recognize the key... Had two dealers tell me I needed a new computer... Ended up being a firmware problem... Updated tuner and everything was fine
