Black smoke start up

I noticed a puff of black smoke every time I start the car.
Is this normal, or could I have a possible leaking injector?

The exhaust looks also darker than others. But I was also getting on it pretty hard a few times lately.

You have a modded and tuned car so that might be your new normal.

Maybe, but they said they didn't change anything at the idle/ start up tables..

Tips look normal to me.

What does that smoke smell like? Burnt fuel or burnt oil or nothing (water vapor)?

black smoke is fuel, blue is oil.

I should add that this is similar to what I see on my car.

You probably have a lot of carbon buildup in the exhaust like me and probably every other DI Camaro.

I noticed black smoke coming out the back of my car when I romp on it after a day of easy driving. My car is 100% stock.

Same here. It's the new normal.
