Here is a small idle clip that I took on my first startup!
I recall renting a new Express Van last year about this time and the throttle response was terrible. For a 6.0L engine, that van was very slow on acceleration. We logged data with EFILive and found a very "lazy" tune in the ECM. The commanded spark advance was a huge culprit.
Now my Silverado SS (also a 6.0L engine) is very responsive. My S10 (V8 with 03 Corvette electronics) is also very responsive.
Don't let the "lazy" calibration work from GM deter you from drive by wire. Not only is that the present/future of throttle control, but it has its benefits when embrace it and make it work for you.

Ok so the latest update. I recently purchased HPtuners, so I could do updates through email to my tuner. He had to adjust a table that was keeping me from getting any throttle response. Car now idles much better and at a lower rpm. I readjusted rocker arms, and set our for a small run. This car is a rabid animal!
It is in desperate need of an alignment and I need to re bleed my brake lines. The video does nothing for the way this car sounds. It is 10x louder in person. I am almost afraid it is too loud. I am not running a cat with gmmg. I might have to quiet things some on the car. I will wait till final tuning to make that decision however. I can't wait for this thing to get to the dyno.
Here is the vid to show improvement of idle. Keep in mind this is a rough tune right now and will be much better after the tuner gets his hands on the vehicle.

Thanks man, and thanks for the replies everybody. The sound has more to do with the GMMG and exhaust setup. No cats BTW.

Thats pretty cool, what were Mike and Jay's thoughts on the set up? I remember Mike had mentioned your car, but had some hesitations about the set up. I have the EFI 24X on my h/c TA

I am sure there is a learning curve on setting up 24x base tune, but once that's down mike nailed the tune fast.
He was impressed with the power it put down also. It's nice seeing LT1 making good N/A power.
