Any advantage to dyno or street tuning a completely stock C5?
I know many vehicles can benefit from a tune even if they're completely stock. Is the C5 one of those vehicles?

you might pick up 10hp so not a whole lot but some of the driveability bugs can be worked out like skip shift, fan on/off settings, throttle response, shift point in autos, etc... so yes there is a benefit but whether or not it's worth the $3-400 depends on the owner of the car

the Auto vehicles really benefit, firms up the shifts and boost line pressure makes them shift sweet and last longer !!!! the ECS 150.00 mail order tune is a great way to go !!!!!!!!!!!

Dyno-tune to get your numbers if you plan future mods. My first (stock) tune was street - and that included tweaking the fan temps and also install of a 165 thermostat - made a BIG difference. 2nd tune (intake + exhaust) was on dyno to get numbers. Cam + heads could be in the future...

I have a regular street tune on mine (shift points, fans, fuel/timing, deleted rear O2s, etc), really woke the LS up compared to stock. WELL worth the $100 it cost me.

I've had tunes on virtually every single vehicle I've owned, and as it relates to relatively stock vehicles, from a SOTP perspective, if you have an auto trans, you will get a pretty nice improvement from adjusting torque mgmt alone. The drivability improvements off the line and quicker shifting on an Auto make it very much worthwhile. Obviously, that does nothing for the M6 so that potential is off the table. For a M6, unless you plan to go with a cooler T Stat, and plan to do some other mods, you might want to hold off, imho. I got my C5 M6 done and was underwhelmed.

A lot of new owners are scared of the relatively high temps it takes to operate the high fan speed for the radiator and a tune often brings those low and hi speed start points down, despite OEM operation not hurting anything. The A4's shift points is a big help also. I'm repeating a lot of what's been said.
It also depends on the car. Going off the post above it's sometimes best to wait. A '97-'00 car would be better suited for some initial mods before going with a tune, like an LS6 intake swap. There's a lot you can do initially and then get a tune to accompany the mods, rather than spending money initially, only to then modify down the road and need to spend more money on another tune.
A local tuner may be the best way to go also, especially if there is a local Corvette or LS specialist. I know a guy that charges a rather average initial fee for a tune, but anytime adjustments need to be made and such it's a small fee. That's sometimes comparable to having to deal with set price "mail ins".

Pointless!!!
If you're stock with an auto trans you might see some benefits but even then you're better off to spend for a mail order tune at about $150 vs $600 or so for a properly done tune. If your car is manual, save your money...

I would probably wait until you are ready to do some additional mods before spending $400-500 on a dyno tune. As an alternative, get a mail order tune for a lot less cost to see some improvement on a stock vehicle.

$600 seems a tad steep for a basic n/a setup but regardless you need it... if headers are still a ways away you could get it tuned now and when you get the headers done they should only charge a small fee every time you go back for small changes... talk with the tuner first to make sure but most of them work this way

I was annoyed by the throttle delay in A4. Friend suggested a speed tune. Tech at a Vette speed shop said I wouldn't recognize the car afterwards and he sure was right.
