Has anyone tuned the new 6.6 L8T gas engine yet in the Silverado or Sierra trucks yet? If so what kind of power are you getting out of it.

Has anyone tuned the new 6.6 L8T gas engine yet in the Silverado or Sierra trucks yet? If so what kind of power are you getting out of it.
Roughly same power gains as 6.2 l86? the compression hurts them just a tad, but I like them
How much HP? I would like a little more HP on my 6.6. I have never seen the HP gains on the 6.2.
Do you think it is worth tunning?
Checking in on this, how is the tune on these stock? Big PE delays and such like the older 3/4 ton trucks? Or are they pretty well dialed in like some of the newer 1/2 ton stuff?
