I mean, I have a general idea what it is but:

Who performs them?

Where are they performed?

Do they involve the installation of a chip?

Does a tune void the GM warranty?

Is it a one time deal or are they only good for a period of time or number of miles?

Is there any hard data that shows it benefits perfomance?

How much should one expect to pay?

Thanks in advance

wow ... just wow .... normally HATE those who say you should search ....

but since you spent so much time to post your ?'s .....

Yep.

Going to be brief! A "tune" is modifying a computer/s in your car, engine, trans, etc. for improved performance! GM downloads are OK, others are not. Contact local Vette club to give advice on local tuners in area. Check "performance shops", ask for "tuners", look in yellow pages near or in your city. Put your city and location asking for tuners in your area on CF.

TUNE = LOST WARRANTY, period per GM, they check computer printout and send to GM on your car if suppected and GM gets copy before approving suspected repair or repairs or possible "red flagging" your car VIN #. Dealer has to get approval for major warranty repair or dealer may have to pay for it, their loss. Under unusual conditions, sometimes GM pays, most likely not. NON engine, drivetrain, etc. is normally coverered if NOT affected by tune directly or indirectly, dealers and GM option on covering.

Final: YOU PAY TO PLAY!

Beatles...Hey Judy, that's a good tune.

Not sure if your post is a joke or whether in spite of all the performance info available on the Forum, you're really this clueless, but I'll answer you questions simply as I can. A "tune" is an electronic adjustment of the engine & or transmission control modules in the Corvette. The purpose of such adjustments is to improve performance and/or better match the electronic settings of those modules to other modifications that may be made (i.e. headers, after-market exhaust or intake, cam, etc). Tunes are performed by performance or competition shops, with or without use of a dyno. The tune does not require installation of a "chip", but does override the GM factory settings in those modules. Thus the concern voiced about voiding warranty. There's much that's been posted about whether or not that's a true fact & the answer appears mixed....mostly dependent upon the nature of the warranty work & "friendliness" of the service manager. Once done, the tune does not require any "refresh" & the original factory settings can be restoreed if desired. Cost is generally in the $100-$200 range, although will vary from shop to shop. Finally, does a tune benefit performance.....absolutely! Most times a tune is done in conjunction with other mods, so it may be difficult to segregate the benefit of the tune versus say installation of headers & after-market exhaust, but even with a totally stock drivetrain, a tune by a good performance shop tech will result in improved power, driveability & even fuel mileage. There's certainly much, much more available on this subject so I suggest you do searches on the Forum or get involved with a local Vette club who will also recommend a good local shop if you decide to have the work done.

Thanks both to you and 2006c6Keller for having the courtesy to answer in a serious manner. Yes, I am clueless. Guess it's not okay to ask dumb questions here. I'd just rather that if others think the question dumb they just skip over it and not bother to respond at all.

I get it now, thanks to your answers. At least for now, tuning is not for me, especially if it risks voiding the warranty and who really knows what the longer term consequences could be? A have to believe that if there is easy horsepower out there the General would have built it into the original design. I'll wait for the General's own tunes in the form of NPP, the LS3, new software for the autos that showed up in 2012, the new LT1, etc, etc.

Thanks again for being gentlemenly.

I find this forum to be the most informative of all the Corvette forums and I have learned a lot in the little over 6 years I have been visiting it. But there are those that true believe that they are the elite and have to post negative comments to just about any post that asks a question. I believe that if you find the question not to your liking, simply hit the back button and look for another post. I simply cannot understand the rude, condescending comments that some members feel they need to post.

I guess that is the internet, when you sit behind a monitor and not face to face you can try to show superiority.

Glad you got your answer..

Oh, one last point, the SEARCH function is not the best thing going. Although some seem to think it is, I found that many times if you use Google instead of the search here you will find it supplies you a link right back to this forum and a post dealing with your question.

Plenty of people know what the long term consequences could be, next to nothing on a stock car. This is not a new thing.

There is easy horsepower out there, at least a few in a bone stock car with a proper dyno tune. The calibration from the factory has to be something they can apply to tens of thousands of cars and have them all run in an acceptable range. Cars vary build to build and what one car thrives on another will knock. With a proper dyno/street tune you are getting a new calibration specific to your car which can help extract a bit of untapped power.

There is also easy horsepower in bolt ons/cam swaps etc and the reason they don't come that way from the general are NVH, the EPA and driveability.

Though sensors are the same some will read slightly different than others. Its why one tune for your car may not be the exact same for mine.

BWF07:

Thanks for your comments. Glad to know it's not "just me". Same ole everywhere, I guess....even among Corvette enthusiasts.
Meanwhile, I've learned precisely what you are talking about regarding the search function. I too now just search on google and it directs me to the appropriate forum thread even though the forum's own search function can't seem to find it. Go figure! Thanks again.

I am a new Corvette Owner late in life and I also had some questions regarding a Tune and what it is. Reading the forum over time and some of the responses to threads for newbies made me hesitate to ask the same question as the OP. Tried using the search function but the answers were sometimes super technical and not very user friendly. The answers provided above were spot on for people like me. We need to keep in mind that your answers are viewed by many persons who do not respond to the thread but nevertheless find the answers very informative. So for the guys who responded THANKS!!!!!

If you do a Google search I find it also helps to add corvette forum, i.e. C6 Corvette engine tune corvette forum.

That will bring up a wealth of pertinent info.

Even better, search site:forums.corvetteforum.com searchterms

That limits the search to the specfic website.

I had a tuner checking my car today to program it for a 160 thermostat and I have to admit that I was a bit blown away while watching the guy doing his work on the laptop. He showed me all of the files in the tune and its pretty amazing how far technology has come. I remember my 82 vette had a "computer" in it. You shorted out some of the prongs with a paper clip and counted the flashes and that gave you a code that you had to look up. What I saw today looked my the "my computer" area of my PC with all of the directories and sub folders. So much for changing jets and using a timing light......
