I see you're from New Orleans. Are you there now or in Houston? Either way, if you want to come to me, I'll tune it for you. You can either use your laptop and software, or you can spend $100 for an EFILive license so I can use mine. I've never used HPTuners before, but I can't imagine that I wouldn't be able to use it. You can just buy me lunch or something for my time. 
damn i wish i lived closer...im in new iberia now....south of lafayette doesnt mean i wont drive to get this **** straight!
unless you wanna drive here? i would pay you!

if you could tell me where to start or which direction to go......
kinda a guessing game at this point
go out ona long drive maybe 30 min after you are out of fuel trim cells 20-22 which is a few minutes after start up. drive around for maybe 5-10 min and then start to log. log your fuel trims and then go back and make changes to the primary ve, then you have to copy over cells from the primary to the secondary, starting at 20 kpa up to 100 kpa in intervals of 10

Hmm, that's a long way to drive with warrants. I might consider driving up there. I don't know. I wish you would come down here as I'm lazy. 
I drive an 02 Z/28 with a couple mods. If we can work something out, I'd be glad to tune it for you.

Surging with a cam can be due to lower ve near idle due to overlap, exhaust reversion etc.
This also requires additional timing to get more complete combustion.
This is hard to pick up with a wideband as combustion can be erratic. There are some good threads by others about idle tuning with a cam.
You can try taking a look at them too.
