I recently bought a 2008 corvette! It's bone stock, what's the best performance tune??

RecMech

Best tune would be custom.. Find a local reputable dyno shop.

Hands down this is the only way to go -

With canned tunes and mail order tunes there is no way to check and see all the necessary perimeters to make the most RWHP and RWTQ, fuel trims, timing, and a host of other tables etc.

It will generally run around $450-$550 for a complete tune and usually around $100-$150 for re-tunes from your tuner - when you do upgrades -

Thanks,Matt

And if it is a A6, a good trany tune can provide more driveability benefit than the engine tune.

Mail order can adjust. A canned mail order tune no, but if you log and send that to the tuner, then get revisions back and forth, that is just as good or better than a dyno tune. Real world street data is better than running the car on a big treadmill.

but, but, but I like paying $500 for my treadmill time

Agreed , not enough to of a gain for how much money you are going to spend on a stock car, complete waste of money

Go the route Unreal suggests , buy a Diablo, load the Diablo tune and TCM tune , then log it and send the files to Diablo Lew ... total cost is just short of a Dyno tune but you now have the ability to modify many parameters .....Data Log your car , read and reset trouble codes


Lew does a great job on both the ECM and TCM tunes , then you can keep logging the car and send it to him to fine tune

Plus , you can restore your OEM tunes if the need arises ...

If you don't like it you can always sell the Diablo , try to do that with a Dyno Tune

Only thing I would change is get HP tuners instead of diablo, and then use someone like Doug@ECS, Frost, etc to do a mail order tune.

Unreal , how much is HP tuners ?

Do you also need to buy licenses ?

I assume you use a laptop , does it come with the OBD interface ?

I always heard its much better but I never looked into it

Thanks

Depends on version. Plenty of used ones out there too with credits, other wise it is $100 a car to tune a car if it doesn't have any credits left.
New comes with enough credits for 4 cars.
Yes needs a computer, and yes it comes with interface.
