Lost on Corvette Tuning, Need Guidance

Here's an update as to what's going on with the car.
About a week ago my dad dropped it off at the Chevy dealership to get things such as the transmission checked out, as well as the tire pressure issues checked etc. A guy from the dealer took it for a test drive and said the transmission was fine, but they'd check the fluid anyway.
He went to pick it up two days ago, a couple of hours after they said it was ready. He waited there an hour before he left because it wasn't ready. They hadn't installed a new battery like they were meant to, and apparently it had also run out of fuel, even though it was dropped off with over a quarter left!! They also said the ABS issues were caused by a faulty EBCM, or something similar to that nature, and it would cost $9000 to replace. Also, apparently all TPMS sensors are out, and that's $1100 to repair. I couldn't believe it.
He went back yesterday to pick it up. He found the casing for the key cracked, so he's had to buy a new fob out of pocket. That wasn't the worst thing though. On the way home, the car was stuck in either 2nd or 3rd gear (apparently it was 3000rpm at 60mph), and wouldn't change at all. He tried sport mode, and tried using the paddles, and neither worked; wouldn't shift gear. Park, reverse and neutral were fine. I'm thinking maybe the dealer didn't refill the trans after draining some to check the fluid, but I don't know. We're both really not happy at this point.
Any ideas?

wow 
If the battery is not good, I couldn't follow if it was replaced, so I would certainly get a good battery in the vette, because it makes all kinds of wierd things happen if you are getting low voltages.
It almost sounds to me like there are ground issues too. If you can find a diagram, I would check every ground on the car, by scraping the paint and reattaching them.
But you also really need to get the codes read and interpreted by someone you trust too, it really sounds hokey from that dealer.....
It's bound to have a bunch of codes, from all of this stuff going on.

Another update.
My dad went to run/drive it yesterday. Battery was flat. Something is obviously draining the battery, so now we just have to figure out what it is. We've been looking around for a good shop to take it to, who can hopefully help us out with all of these electrical issues.
New TPMS sensors (from eBay) have arrived, so those have to be installed.
I've been doing some reading and it turns out the car must have gone into limp mode, as it sticks the transmission in 3rd gear when that happens. 3000rpm at 60mph definitely sounds like 3rd. Unfortunately, because the battery died, we would have lost all fault codes...
I'll take everyone's advice; after these issues are sorted, I'll look into a tune. Hopefully they're only small issues, just some wiring that needs work. We didn't realize the extent of the issues, but we did get it for an extremely cheap price. It'll be great to drive once everything's fixed.

Today my dad fired the car up (had to leave the jump leads on for about 5 minutes so that the car had enough battery to start!) and plugged in the OBDII scanner he bought from eBay.
Luckily, there were no codes found. I understand there wouldn't have been any after the battery ran out, but at least it didn't develop any whilst idling/driving slowly around the block. I also understand that it most likely can't read transmission codes.
During the drive around the block, the transmission behaved itself as usual and didn't go into limp mode, which was good.
On the OBDII scanner it could show you live data from what the car is seeing. The STFT and LTFT's were both at 0, and something (I forgot what) said 'OL', so I'm assuming the car is running in open loop even at idle. Coolant temp was 205F, and IAT was 95F, so temps aren't the reason why it was in open loop. The O2 sensors were hovering around 0.8 volts. Any ideas here?
Also at idle, load was at 30% (sounds high, my other car idles at 20% after a tune) and the MAP was reading 41kpa, which also seems high.
Does anyone have any idea what's going on here? Has the car been tuned previously and is why it's running open loop, or is there another explanation? All input definitely welcome!

You need to find someone with a quality scan tool or a TECH II.
Given all the trouble you described, no cheap code reader is going to help much.
Not sure where you're at, but if you're close to me it would be worth the trip.
These cars are really complex, but given how many strange problems we see, I'm
sure we can save you lots of time and money.

Gotcha!
I always wondered why my TECH II cable was soooo long, but YET not long enough!
E-mail me some of the details and I'll see if I can help give you some direction.

I've sent you an email (well, to corvette-doctor@). Hopefully you have time to read it, and don't get bored/distracted easily...it's VERY long.
Thanks again!

The learning curve on tuning is huge--Even if you have basic computer knowledge and basic engine tuning experience---A stock tuning file has apprx 450 tables in it and another maybe 400 in the trans file (if an automatic)----
It's not as easy as adding or removing timing or fuel---There are many redundant tables that have multipliers -deductions and adders to compensate for various situations---If you love to tinker and are willing to gamble with making an error that may damage your engine--and spend hours learning the system then it may be for you
You not only must learn all the tuning tables but must also learn how to effectively use the "data logger" so you can get real time data stored and make adjustments according to what the data logger says
As far a the Vararam goes--Most CAI will learn out the fuel trims after about 50 miles of normal driving---The Vararam can change the incoming air flow change so much that you'll get lean codes and must make a MAF table adjustment to compensate--Typically a lean code will pop up when the leaness or richness is beyond 20%----
It really doesn't mean that it's flowing 20% more air( as that would be amazing) but because of the changed air path and relocation of the MAF sensor the readings are changed and or inaccurate--

Learning to tune is something that doesn't come with a few weeks or months of trial and error. You'd more than likely damage something in the meantime in your innocent ignorance.
I made the mistake back in 07 and bought HP Tuners thinking that it was something I could teach myself, which wasn't the case. Expensive lesson, but far cheaper than blowing up my motor tinkering around like an idiot. There are Tuner Schools available that will give you a base knowledge on how these things work, but it still takes YEARS AND YEARS of practice before one would be considered qualified to tune a modified Vett.
I mean zero offense, but it sounds to me like you bought a problem car, regardless of what you paid. Take it to a Corvette Specialist and no one else. There are people that can work on your car, but a Corvette Specialist will know exactly what's wrong with it immediately and without guess work. The same goes for Tuners, stick strictly with a Corvette Specialist and NO ONE ELSE or you will regret it.
Chuck Cow is one of those specialists, and someone that can do both diagnose and tune if required, though it sounds to me like the guy you bought your Vette from sold you on the fact the the issues with your car "can be tuned out, no problem". That doesn't sound like the case here, it sounds like you bought someone's nightmare with the promise that a tune can fix it.
Again, no offense, I'm simply calling it as I see it. Best of luck man!

A problem car is definitely what we bought. Unfortunately, there's no Corvette specialists in Qatar. We just have to take it to a couple of different shops and hope one we go to is up to our standards. Trust me, tuning wise, I'd only go to a Corvette specialist. That's why mail-order, or tuning myself, are the only options.
We came into the car knowing about some of the issues; some (such as the discharge) are new discoveries we had no idea about. Some are more serious than we expected/were told, too. We'll get it (mostly) sorted eventually.
Thanks! I appreciate the help.

I replied to your e-mails....
No offence taken at all. I understand what you're talking about, and the learning curve involved with tuning. As I posted previously, I've tuned our other car (GT500 with TVS supercharger and intake) so I have some experience.

It turns out that today is a public holiday and the shop's busy for the next two days, so it'll have to be sent in on Sunday/Monday next week. As I said, once I get the codes, I'll send them through to you. It'll be fixed eventually!Thanks again Chuck!

Just another quick update.
The codes were read. Here are the results:
Corvette Tech2 codes
C0110 pump motor circuit activator stuck
C0550 dynamic rear proportioning performance
C0281 same
Engine
P1682 ignition 1 switch circuit 2
SRS airbag system - 11 fault codes - many sensors, the coil etc
Any thoughts? Thanks!

Good news! No more warning lights (other than airbag), and the horn works. No more "service active handling system" "service ABS" "service traction control system" warnings! Win!
Bad news. My dad drove it around for about an hour after picking it up from the shop two days ago. He went to drive it today (as it'll eventually become a daily driver). Wouldn't start again. This time it cranked, but nothing happened and it didn't start. Checked the fuses and relays relevant in the fuse box, and they were all ok. Very suspicious...
And it goes on.
EDIT: there were no codes read from our cheapie OBD2 scanner. Also, my dad wasn't able to hear the fuel pump priming. However, that could just be due to difficulty hearing it/not turning ignition off/on properly.

Whoops, didn't see this. Thanks for the reply though. We took it to a shop and they said they found 3 different electrical leaks. So far, it seems they've fixed that issue. It was taken back again afterwards and they replaced the motor mounts with aftermarket ones we supplied (Hinson I believe), re-programmed our new keys, replace the airbag coil (being in Qatar, the horn is VERY necessary!) and had a new EBCM fitted.

EDIT: there were no codes read from our cheapie OBD2 scanner. Also, my dad wasn't able to hear the fuel pump priming. However, that could just be due to difficulty hearing it/not turning ignition off/on properly.
2008 C6 will turn off by itself. I have replaced a few BODY CONTROL MODULES (passenger footwell fusebox) when there were
tons of crazy codes.
You won't fix this without a good code reader. Get one for sure. Even a Chinese TECH II and CANDi module from E-bay is best.
Have not had to replace any C6 ignition switches yet, but C5 and most other GM cars suffer from this and you'll always get all sorts
of crazy *** problems you might never find...
Good Luck.

Looking forward to (hopefully!) picking up a tune from you once all these issues are resolved!

The 08 C6 A6 turns into a monster...
Just tell me when you're ready.
