Cam installed, is this tuning or mechanical?
I realized from the beginning that without a dyno tune it would not be perfect, and after a couple hundred miles of driving, the tune did get better. My problem is that the car always has a tough time starting and staying running. When I start it, it cranks right over, but unless I keep it at 12-1500 rpms for 30-90 seconds, it will die. If the AC is on it's worse (due to the added strain I guess). Even driving around town, it runs great, really strong, but if I'm making a turn at low or no throttle (coasting through an intersection) it dies 50% of the time.
I've heard mixed results about tuning and drilling the throttle blade bypass hole larger.
Does this sound like tuning will fix this or should I try drilling the hole?
Thanks all, I appreciate the help.
If I could have a tune that just solved my idle and start issues and din't cost $400-600 that would be super. But alas, my searches have been in vain.

I have never heard of anyone just strapping a car down and romping it WOT without first resetting idle, part throttle, VE tables, MAF calibration ect first.
My tuner did all of this on his dyno...that's what I meant by dyno tune.

Like mentioned before, they will see where the car stands (With the Mail Order) and go from there, adjust or change whatever they need to.
Good Luck!

My similiar size cam does this with a dyno tune with a well respected tuner on here. I know it can be straightened out but will just take time..... In all fairness I live a ways from my tuner and he has not really had a chance to tweak it for me.....
