Default Stalling at idle

Hey guys, I have a LS3, cammed, stock fuel setup, NGK T5 plugs, SD tune. It sometimes dies when I clutch and come to a stop. Sometimes it doesn't do it at all and it runs fine. My tune guy says the tune is good and I believe him to be correct. So far I have swapped out the o2's (Denso's), Plugs with a fresh set of NGK T5's, air filter, and soon the IAC (Because current one being used is Advanced Auto crap).Can anyone suggest something for me to try or look into. My A/F Ratio looks good around 14.50

Would going back to a MAF setup help this issue? If so I would have to start looking into what I can use, Stock unit wont cut it.

I apologize if this is in the wrong section, feel free to move it if that's the case.

Thanks,
-R

What are your cam specs?
IMHO, it is the tune; perhaps how the Throttle Cracker settings blend into the Adaptive Idle settings.
I had my previous engine tuned well with its 9* overlap cam, but with my new 19* overlap, 102 LSXR and 102mm TB, I am punting with my SD setup and purchased the 100mm MAF kit from TSP. Thats why I am asking how big the cam is.

Honestly I wish I could tell you the cam specs, LG doesn't show their cam specs and I haven't been able to find it online. I would assume someone somewhere has put it on a cam doctor before. It's a LG G6X3 112LSA

Sometimes the car runs great, it's a 50/50. Half the time it runs good, the other half it stumbles and stalls.
