Opinion on Mail Order Tune
As with everything, you get what you pay for in a tune.
For the most part, tuning is tuning. If they have software for a chevy, they can tune your vette, and you're better off with a dyno tune. Where you need to be careful is if you go FI or N2O, that the tuner knows how to tune for power adders and has experience with what you are running.
Because we don't understand the tuning thing we don't know what questions to ask so we we are unable to decide what is best.
My suggestion is to make the investment in the software & time to learn it, just like choosing your cam so you can at least do the speak.

Doing your own tuning is like doing your own mechanical work -- very rewarding, much easier on the wallet in the long run, etc. Tuning has a steep learning curve, mostly because of the lingo, and the software packages themselves, but if you can tune a carb / distributor car, you can tune a PCM controlled car, IMO (maybe not straight out of the box, but still).
There are numerous sites with walk-throughs for new tuners and both EFI Live and HP Tuners have large forums with lots and lots of dedicated people willing to help you out.
On top of that many mail-order tuners will customize their tunes for you (provided you have the same software). They send you a tune, you do some logging and send that to them, they adjust the tune and email it to you, you write the tune to your PCM, rinse, repeat.

Which software to get is a matter of preference. I've used both, but now use EFI Live V2 -- primarily because when I needed to get deep into custom tuning for the TT truck, HPT did not yet support custom SD tunes for my OS. They are pretty differently laid out, so once you pick one, you get fairly specialized into that way of thinking.
For an NA car, you can easily "start small" with the tuning bit and work your way into more advanced stuff as you get more comfortable with the process, etc.
