Tune vs TB & TC
I am new to the C7 family and am looking to do a little upgrading on my Stingray. I am looking in to either getting a tune on my car, or upgrading my TB with a TC to go with it. I don't know which is better or where I should start first, so any input at all would be greatly appreciated.

If I can offer thoughts TB = Throttle Body, TC = Throttle Controller, I say DO IT TODAY. I installed a ported stock throttle body and Soler Throttle Controller (there are many brands) on my 2019 Grand Sport. I’m not a big HP speed demon or anything, but this car drives completely different now. Manual transmission responds almost as rapidly as my electric vehicle. I have not tuned yet due to being on factory warranty.

I have ported intake, ported throttle body, soler TC and Corsa x pipe. The x pipe just made the car louder. The ported intake and throttle body were done at the same time and they made a noticeable difference in throttle response.
The Soler TC was a very noticeable improvement in throttle response.
My next steps are headers and a tune, then a supercharger a couple of years down the road.

Very similar for me as well. Ported throttle body, Granatelli plug wires, SR-1 x-pipe, Vararam TCR CAI, custom exhaust dumps, Soler TC, untuned right now. Sounds and runs more stout. I’m doing ARH or Hooker mid-length headers (California CARB) and a tune next. At some point I’ll add a supercharger, but I’m not in a hurry. This car is plenty fast for how I use it. Good luck with your build.

May want to think twice before tuning in CA https://www.corvetteforum.com/forums...th-2021-a.html
No one seems to have a definitive answer regarding what years are affected. My guess is later C6s and newer.

ported throttle-body can throw a CEL. While they don't really add any power (nor would a TC), they can improve drivability, especially on a manual car. If you are looking for power, you are going to have to tune the car. Any mods can give you warranty issues so be prepared to swap back to the stock TB if requested by the dealership.
Flexfuel sensor and a tune will by far be the best bang for the buck modification in terms of power gains on an LT1, might as well do the CAI while you are at it. If you have E85 available around you, that's the route I'd go if you are looking for 30-40 more rwhp for under $2k.

Any documented performance gains you can share? Dyno or ET's and trap speed to confirm the improvement? I don't doubt there are, I just like numbers and am seriously considering this since I have some mods that would benefit from a tune.

A tune will void any warranty you have. They will know! I’m gettin a Soler TB and have a Soler TC. I think it’s the way to go, especially as a first step. Then drive the car for a while and enjoy.

Everybody already knows that. Ported TB amd intake made a noticeable improvement in response and may have added a little power. Then I added a Soler TC and that really woke up the throttle response. Now I am ready for more. My aftermarket ext warranty may get cancelled of I do. My car is too old to have a factory warranty.
