ok every video i watch there seems to be A ToN of smoke comming out of teh exaust

on my car i tuned it perfectly but i dont have this much smoke coming out Is this a problem?

You answered your own question.

If the engine is tuned perfectly you shouldn't need to worry about smoke, temp etc as you know the engine is recieving enough lubrication. Also, smoke will become more or less visible in different temps, humidities etc.

as long as there is smoke under hard acceleration then ur alright...u dont need tons of smoke all teh time...that means ur runnin rich

also depends on what fuel you use, ODonnell for instance, seems to have a very defined smoke trail.
