Honestly, no.....
Please offer some specifics, including mpg changes.
I'm considering this, for a totally stock C5 M6, but while understanding the procedure, there's no what behind the wow in any posts.
I understand the factory tune makes allowances for various fuels, etc. while ensuring the emissions are licit for many years. I'm not displeased with the car now, but always looking for improvements.
How does the driveability of a base LS1 get expressed? Seems time-wise to offer many of us more specifics versus everyone calling. Isn't that part of why we come here?

Honestly, no..... I feel that everyone has a different understanding of what's going on here and what's got to be done.
Most people miss 90% of what I have to say if they don't call.
The way I see it, people who could not be bothered to call.... are less likely to purchase anyways.
There's 1,000s of pages of info about me on here and all free to read in your spare time.
I'd lose way more time posting and re-posting what's already out there on the forum.... than if I was to spend a bit of time
with those that call as those are the people who seem LESS THAN CASUALLY interested.
I can talk to you for 5 minutes or 2 hours on the phone..... makes no matter if you're interested....
I'm available 10am to midnight for anyone who wants to call....
I'm always here.

My experience of working with Chuck ....
...... has been very good. 
Trying to figure out what I needed to know to select a tuner was just getting overwhelming.
Who is any good?
How far away are they?
How much of a Saturday will I have to spend on this?
What about when I get headers? Or a new air filter system?
I decided to bite the bullet and pay the admission price to get the concierge treatment that Chuck provides. He is in demand, but you really can reach him by phone until late at night. And you never have to remove your PCM, wait for it to come back in the mail, and then reinstall it. Yes - your car remains drive-able while Chuck does his thing with your tune files.
When it comes to my Corvette, if things are done right the first time, then I shouldn't have to spend more money for the same thing later. Chuck really knows the C5 LS engine, and the CoW Booster was the right choice for me.
[BTW - During my own due diligence I saw that there are a couple of jerk-wipes out there who have posted negative comments about Chuck (somewhere): they must either be competitors, or just totally unreasonable.]
Good luck with your decision.

Running leaner and/or advancing the timing will make any car faster. I presume that's what's behind most of these "tunes".
Problem is, you risk engine longevity. You may only get 75k out of the motor rather than 150k or 200k+.

The factory version of the C5 (and the Z06) are great starting points. Bang-for-buck they are hard to beat.
It is great that this forum and various vendors are out there to help those of us who are on a budget, and like to do some (or much) of our own work.

I called; no answer. IF only the search function worked better.I read dozens of posts and quit as the terms were so generic to be a waste of time. "Great", et. al. tells me nothing, sorry. Chuck seems like a valuable resource to most; unique, as Corvette enthusiasts can be tough to please.
Some call it twitchiness, I call it responsiveness. I don't understand how a tune will affect suspension response. Poly and heim joints on my 6th Corvette was clear demonstration of the loose handling of a stock ZR1 I test drove; a clear demo of factory compromising.

I'll be in the office all week. If you miss me, please send a text to my main phone number or leave me a voicemail.
I'll explain everything to you and I'll even make you a great deal because we launched our Labor Day sale tonight.
Give me a ring. 914-332-0049
