Idle problems can someone help me

[1meangto]

I have a 06 gto I'm tuning with a ms4 cam 239/242, .649"/.609" 111lsa. The car will not return to idle without surging. The rest of the tune is pretty good but thius is just getting frustrating. I've tried to fix this for hours now and can't figure out what I'm missing heres the tune if anyone can take a look at it to try to help.

Little hint with cammed LS2's, leave your underspeed - overspeed spark tables standard. If you reduce these like tuning an LS1 the engine will hunt like crazy.

I haven't touched those tables yet.
