I defiantly see the low-end response and benefits of the controller. Then I see the addition benefits of the throttle body porting and downstream pressure curve over the OE body. Combined there must be some low-end gains if not HP gain. I assume the ECU will adjust and can recalibrate without having to do a dyno tune.

I'd get a tune and increase the tip in for the throttle and leave it at that. That would make it more responsive without trying to fool the ECM into giving you more throttle than you are demanding. That is good UP TO A POINT. That point being that the throttle opens up and dumps enough power to overwhelm whatever traction you have. In which case, you have a smoke show and go slower.
Is the TB the "choke point" of the intake system? If not, I don't see how it would get you more power. Whether you pee into a garden hose or a 4 inch sewer pipe, you won't empty the bladder any faster, will you?
I have the Solar throttle controller and am very pleased with it. Several other guys in our Corvette club have it and are also pleased with the way it wakes up the car.
The Basics,
Quicker throttle response: The car feels lighter, more eager off the line, and more “connected.”
Perceived power increase: You’re not making more horsepower, but because the throttle opens faster, it feels like more power is available sooner.
Customizable modes: You can soften response for daily driving or make it razor sharp for track or
Why It’s Popular on the LT2 Corvette?
The LT2 is a high-revving V8 with plenty of grunt, but some drivers find the factory pedal mapping dull at low speeds.
The Soler controller eliminates that “laggy” sensation without the need for a tune or permanent ECU flash.
It’s reversible and doesn’t alter the ECU — so it’s usually considered warranty-friendly (though technically any modification could raise questions with a dealer).
Bottom line: A Soler throttle controller doesn’t increase engine performance in terms of horsepower, but it improves throttle responsiveness, making the LT2 Corvette feel sharper, more immediate, and more fun to drive. It’s all about perception and control.

How many people have a warranty? Also, AFAIK, Diablo does not alter the file they look for without foolers that tricks the ECM.
Just do both, but if you plan to go any further you might want to consider a bigger throttle body. If you want to do a CAI and the MSD manifold you can go bigger.
I have a question about the throttle controller.
Recently, I did a bunch of work on my Z51. One of the things I repaired was replace the down pipe with damaged catalytic converters with new high flow cats down pipes. After an issue with the O2 sensors were resolved almost everything is back and even better now, except the idle rpm. It is around 1150 now.
My question is, will the throttle controller allow me to adjust that setting, without having to take it to dealer?

No, it won't adjust the idle. It only adjusts the throttle response.
Looking at Soler performance controller and/or 91 mm throttle body for my 2019 Z51. Can't decide which to get so thinking on both. Any suggestions.
Agree with those who recommend BOTH. I remain happy, having added them to my Z simultaneously years ago.

There may be marginal discounts available from time-to-time at other vendors, but I see no reason to look further than Soler Performance. They offer maximum Throttle Body (i.e., New, Exchange, Refurb, Rework, Extended Warranty) and Throttle Controller (Extended Warranty) options. @Mike@SolerEngr provides unbeatable customer service and, when I bought, there was a discount available if you bundle your TB and TC purchases.

You have some other problem that needs to be found and fixed. High flow cats should have yor RPM that high. Warm idle is set around 500 rpm from the factory. I actually bumped mine up to 600 as i think its a bit smoother and helps prevent that off idle dead spot.
