Default Mod list, help me decide on which way to go on tune

Ok so I have finally reached the end of the build... For now on my 2008 EC. I'm wondering what YOU would do in the direction of a new tune.

5.3 Stock short block 25k miles
TR219/224 601/607 115 lsa
PRC 8501 dual springs
Yank 2800 stall
Vette servo
Pacesetter long tubes
ORY
Gibson stainless catback
LS7 lifters
DOD delete
SLP CAI
Comp Cams trunion upgrade
4.11 gears
Innovative Wideband
MSD 8mm wires

There is a shop a couple hours north of me in Raleigh NC that has put out some magazine worthy builds that has a pretty slick dyno setup and the price seems very reasonable. I currently have a pcm4less tune on it now and haven't been very pleased overall since installing it. I have around 3k miles on this setup with no issues. I am really thinking about another one of our great sponsors for another go round' with a mail order. For some reason I just feel uneasy about someone else strapping my moneypit down and running the **** out of it. I have done all these mods myself and I guess Im just fearing that something would fail. Don't get me wrong, I do very good work and have cut not one corner in any of my installs. I've been wrenching my whole life and this is definately not my first engine build. I always second guess myself IMO. What are some benefits of dyno tune vs a datalogged mail tune, other than a paper power graph? I guess Im just needing you guys to chime in and give me some opinions on what YOU would do.

Why not just buy efi live and learn to tune yourself. That way you can tinker with it and fine tune it like you want. Its well worth the money.

I have read through the tuning threads on here and whewww! Seems like some intense stuff. I would love to do it and learn the ins and outs but I just don't have the time right now. Could you get a tune pretty damn close just using a wideband to tune off of?

Thats the most important part is the air/fuel ratio.. Wideband is a must.
Its alot when you start but it sure is nice to change something when you want.

If it were me, I'd get a dyno tune.

Tuning it yourself would be great. Problem with that is, the learning curve is fairly steep. I'd hate to put off seeing the results of my work b/c I was trying to learn how to tune it. Or make some kind of mistake tuning it, causing some other kind of problem.
