Every once in awhile under hard acceleration the car will push to the left even with all the traction control and stabli-trac off and in race mode, anyone else have this issue or recommendations?

Only if I have wheel spin. It doesn't take much spin to make the rear follow the slope of the road. Most roads are raised in the center for water runoff. If you try it in the center of the road it will most likely go straight and if you try the left lane, it will likely go the other way.

There is always the possibility of other causes, but those issues should be noticeable way before full throttle.

If I was in your shoes I'd have my alignment checked first and see if it's aligned to specs. A lot of ZL1's are coming off the truck with toe issues causing these issues. Have the dealer or someone else check the specs if it out of spec I'd have the dealer align it up and see if it works.

Is that directed toward me or the OP? I don't have an issue with my car. It goes straight unless the rear is sliding around from wheel spin.

Check tire pressures before anything else. Check them cold.

Here is what i found, when the outside temps are below 80 degrees (our winter) my car will pull hard to the left (under hard acceleration) with both hands on the wheel, then come back in a straight line, this changed 2 weeks ago when temp went well past 80 degrees mark, had the car out for some fun last night, car now is well behaved no more pulls to the left.

Think temps have some thing to do with the pulling?.

How often do you check tire pressures? And I don't mean from the TPMS readings on the dash.

I have yet to see an onboard video of this happening. (not saying it isn't happening, but at least we can take the subjectiveness out of the equation.)

That is what I experience from time to time, but is usually in 50 degrees and below, where the tires have less grip than when it's warmer out. I have also noticed where it does that, the road is ever so slightly sloped to the right (sometimes so slight that you can't really see it). If I go back to that exact same spot and move over to the center of the road, it'll stay straight (maybe wiggle side to side a bit), and if I move all the way over to the left, the rear will go to the left and I have to correct to the left. Now if I do the exact same thing on a warmer day or have heated my tires up from either hard driving or a bit of a burnout, the car just hooks and goes. No movement from the rear and no correction needed, so it all seems linked to slight wheel spin. The movement/wheel spin is slightly more pronounced when TC SC is off than when they are on, which supports the wheel spin I feel.

Another thing that can cause movement in one direction, besides the slope of the road is different amount of grip between the rear tires, that can come from a few things. If one rear tire has more air pressure than the other, one tire has ran through dirt, water, etc that would decrease grip, or if one tire is loaded more than the other (one front tire on a bump or in a dip) the car will try to go in the direction the tire with the most grip is pushing it. So if the right rear has the most grip, the car will push to the left. I experienced this to the extreme at the strip on the night I ran my 10 sec 1/4. I had been driving around the water box all night and my burnouts were always straight as an arrow. After I ran the 10, I took my son down the track with me, and when we pulled up, several people were standing around for some reason, so I couldn't drive around the water completely, and the driver side went through the water. When I did my burnout, the rear of the car slid hard to the right because the dry right tire had way more grip than the wet left.

thanks all for the info or insight as to what it might be
