im just courious, my truck has been doin this since i did my egr delete. i plugged both ends of the egr cooer itself so it would pass smog tests and look stock. when i start up i get a little "cough" of white smoke, when the vanes on the turbo close it goes away. could this be just extra fuel from starting or coolant?

this is the fun game about diesels is so much to know about smoke and its colors and smells haha.

any input is help

thanks guys
