My Corvettes have both been manuals so I can't speak to the automatic transmission issues. But back in April I traded my 2001 C5 on a 2017 C7 Z51. I never found my C5 to feel "slow" right up to the day I traded it. The C7 felt so much faster and more responsive than the C5 did that for the first week with it, it was almost intimidating. Now I've gotten used to it but no way does it "Lax".
OP, you also mention "always annoyed me with RWD" but its really got nothing to do with being rear wheel drive. Nearly all of the highest performance cars in the world are RWD (with some AWD) thrown in there.

JerryU: Hmm. There is some slip in a torque converter but the amount in a clutch, or angular twist in the driveshaft, or the nonexistent time it takes for meshed great to transmit torque would not be detectable, IMO. Granted in a ProStock drag car the front lift does take a small amount of time but not significant in a Vette, IMO.

Ok - please be kind all, need some advise. The one thing that has always annoyed me with RWD is that, at times, it feels like there is the delay between press pedal and go. I got the vette because it has a lot of power and its light for a sports car.
I feel like the car either is very lax or I have to really push it then its like I am racing.
Some rare times I can hit the pedal just right and its like the car moves with effortless grace (15-40mph range) like it has power and it needs next to nothing to move like a cheetah.
My question is this, is there something I am doing to cause this? Is it heat soak or to much AC blowing? Have I become use to the power and no it feels less now? I know this is all very subjective. I just feel like there are times when I accelerate its like pure class and it takes nothing for the vette to move through traffic and some times it feel like I have to kick it harder then I think it needs.
Any suggestions? At times it feels, to me, like maybe the gas pedal is to stiff. I don 't know.

I decided to purchase and install the item because it has been lauded on the Camaro boards as a "night and day" difference maker. I have to say that it has made a big difference in the way the Corvette responds.
PM me if you want details.

Firat guess: you are engaging that aggressive drive mode where the automatic holds the rpm longer for sport driving? Doesn't that happen automatically? Could be creating the 2 different feelings
Second guess: What about cylinder de-activation? Could it be slipping into v4 mode sometimes and making the difference

Unfortunately I don't have a picture of my Stingray coming out of the hole, but, to prove my point here's one of my C6. If you don't think that motion doesn't take time you're mistaken. On the street just giving the gas a little extra will act like a slight delay. I've noticed this with every Corvette I've owned both manuals and sticks.
On 0 to 60 runs with my ProStreet Rod you do perceive very small "delays" and differences in run to run as you no doubt do at a drag race start. I can "feel" the difference when changing the hole positions of the 4 bar rear links and my adjustable front shock settings. In fact spent quite a bit of time trying to reduce what was an "intolerable delay" with the the vacuum secondary 850 carb that came with 8.2 liter crate motor to improve the initial response. Finally solved that with an 850 double pumper but still needed two 50 cc accelerator pumps and the proper fast response reduced volume pump cams! I'm sure you're right when drag racing your can perceive hundreds if not thousands of a second differences coming off the line!

Jerry I do agree with the pedal by wire response on the newer Corvettes are calibrated, it seems, for "economy". However, even though it may seem like a long time in hundreds of a second but actually be in thousands of a second especially if you're in a hurry. 
Plus this person also lives in Florida, and the AC is almost always on with outside air heavy, humid & warm. 
All things which make any car feel sluggish.I guess I've just grown used to it.

OP, I felt the same way about throttle lag in my 2013 so I installed the Diablo Sport tune (~$350) and the Sprint Booster throttle booster (set for track mode) and those helped response quite a bit. The DS also quickened the 6 speed AT shift speed. I also drive in manual sport mode. I'm happy with the response now. Good luck.

"If you want to improve your C7's throttle response, consider the Sprint Booster throttle response enhancer. Features three settings that you control with a switch, to boost your C7's response off the line.
Easy to install, it increases acceleration time by measuring and converting the digital signal and making the electronic control module respond more quickly. You'll feel the difference in pedal sensitivity and how fast this part gets you off the line. This part works with all C7 Corvettes - Stingrays and Z06s."
With a standard shift I just push the peddle more when desired!
Google or call a Forum Vendor to see who sells.
