dropping the hammer from a roll.........SMOKE...... While cruising on the highway, what would cause a cloud of smoke to come out for just that first second after I punch it. But after the initial punch its clean as can be. Than if I slow down and hit it again from a cruise speed, there is no smoke. Just seems to happen on the first one.
The color seems to be white-ish but maybe its a little dark. Its certyainly not black though.

its PCV, valve seals or piston rings in that order if its oil smoke. Somehow oil is getting itno the combustion chamber and those are the only three ways. If you dont have the Z06 PCV its a good upgrade. You could do a leakdown to check the others. Personally I wouldnt worry about a little blue oil smoke. You are driving a racecar! Im sure you can tell if its antifreeze (smell, fluid level etc)
Its tuning (plugs, programming, ignition) if its black.

I also get pure black soot that builds up on my bumper right over each tailpipe. It takes about 1 week to start getting real noticable after I clean it off.
What is that all about?

This happens on alot of cars, doesnt mean theres anything wrong. If its black, then your running on the rich side which is safer for the motor. and if its just a puff, then you just cleared out the motor that had some carbon build up.

The first start of the morning I can see very faint puffs of white smoke coming out for about the first 20 seconds, than it stops and its clear.
Also, if I sit and idle in "park" and give it a good rev I'll get that same cloud of white-ish smoke, but if I rev it some more its almost all gone, just a little on each rev after the first.

Check inside the intake for oil. Flashlight..long swab.

I'm willing to bet a tune would take care of this. Then, if your tune is right on, it's running like a champ, and u're still gettin the smoke on the first hammer drop... I wouldn't worry about it. If you don't smell antifreeze (and your coolant levels don't diminish over time) you should be alright. It's nothing to really worry about. Just get the tune.

There is no exterior visual leaking anywhere, its been checked by two shops and the dealership. Everyone guesses its leaking into a cylinder from a partially blown head gasket.
Can this cause that smoke when I punch it?
Can it cause the pure black soot too?
It is running perfect, quiet, smooth and strong as hell though.

Dude, if you're losing that much coolant than yes, good chance it's coolant in the chamber from a headgasket. Look at the oil, is it milky like a milkshake? When you say checked, did they pressurize the system or visually look?

I wouldn't know where to begin to do that. I guess I should get a new tune and than I can have that checked."
It's really simple. You take off the valve covers, remove only the intake rocker bolts, put sealant on the threads and a little dab of locktite under the washer. Re-tighten to 22 ft/lbs.

The oil is normal color, dark. There is this sludgy looking black stuff that is on the rubber seal of the radiator cap, and a few little pieces around the filler neck. Looks like the scum that you would find in a refrigerator pan. I pick it off with my fingers and flick it onto the ground.
But no white stuff at all, ever.

$65 per hour, figure 2 hours. Most shops around here charge that.
Regarding the oil, you need to drain it and look at it. The sludge is a sign as well although for me I can get sludge buildup by driving in the winter and not heating it up for over 20 minutes.

white smoke = antifreeze. This is confirmed by you losing coolant. First thing you need to do is get a cooling system pressurization test and go from there. You have something leaking coolant into the combustion chambers, really that means cracked heads/block or leaky head gasket. You are probably going to have to pull the heads either way, and inspect the gasket (pray its the gasket).

Will the pressure test determine which of the 3 things it is 100% for sure?
If I'm only loosing a cup of coolant per day at most how can it make such a cloud behind me, I would think a few ounces of coolant would get diluted easily in the mix.
NO antifreeze here.....just straight water. So how can just water even make a cloud?
