For whatever reason, the stock throttle body is dreadful off of idle, at least for many of us. Making a turn from a dead stop to merge into highway traffic where a bit of throttle is necessary my Z06 would first fall on its face, and ten would finally get going. It never stalled, but felt like it was going to.
The Solar throttle body fixed this. Smooth response off of idle, and the car leaps forward from a dead stop.
My guess is the problem lies with the fact the same throttle body is used in multiple applications by GM and is a compromise for each vehicle in which it is used.
Then again, GM may have simply blown it and designed a mediocre component.
interesting. I'll have to give that thread a read, or hope for that person to chime in, because that doesn't add up to me with what I can see so far. near as I can tell they're using the GM stepper on their own plate, which would only exacerbate a granularity issue off idle what with the larger plate. unless they're changing the drive gears in the stepper, I suppose?
skimming that post it looks like actual real R&D put into this, and a lot of good information. very nice. I'll put that on my reading list for later, thanks!
during normal driving its much better, i still sometimes stall when im parking in the garage, its alot of maneuvering to get tight against the passengers side wall.
but seriously once I put on the ported tb and tc my low speed driving was improved drastically.
I did a ported stock TB and the Soler TC at the same time. I have a inclined driveway and the stock throttle response on my manual Z51 made it more work than it should be to smoothly and slowly pull into the garage. The TB and TC combo solved that. It made a very noticeable difference in throttle response without being "twitchy" unless you put it in a very aggressive setting.
I know how to drive a standard and I stalled this car way too many times trying to be smooth and slow from a stop. The TB/TC combo solved that, too.
I encourage you to spend some time reading the info @Mike@SolerEngr made available, along with his answers to previously asked questions.
yeah, so I don't understand this consistent idea of "higher modes are scary and when I floor it the car just goes like hell!"
in mike's post he specifically says "it's just tricking the ecu into thinking you pushed the pedal down further" which, yeah, that's what throttle controllers do. there's zero difference between WOT with and without a controller, unless the controller is capping it lower. it can't raise it.
I really don't understand this fascination with "oh man my car is so scary with the throttle turned up I'm scared to turn it past (value)" -- you get the same effect by flooring it, which some people for some reason don't agree with.

I think it's more the non-linear scaling you can have that gives you a "twitchy" throttle. If 10% pedal is actually 10% throttle but then 20% pedal is actually 50% throttle you're having to be really fine when pushing the pedal. We all know foot-to-the-floor is scary but mid-throttle scary is new.

FWIW, I suggest taking some of the forum hyperbole with a grain of salt. I've read some of the same statements. I take them as little more than exaggeration for the sake of emphasis. (It's either that, or the authors lack experience with high-performance vehicles.)
I've tried EVERY mode my TC offers, at least briefly, and found NONE of them "scary." Some make the throttle numb. Some make it twitchy (which I assume others describe as "scary.") I did NOT feel "scared" or out of control with any of them.
If you're curious, I recommend picking-up one and giving it a try. I suspect you'll like at least one of its modes. If not, their resale value is strong, minimizing your financial risk.

I've got an mpvi so I can just code the ECU directly if needed! the OEM throttle control is acceptable for me as it stands though -- I usually just adapt to a car's implementation anyways. :>
