truck blows white smoke occasionally with my ppe on lvl 4. tuned it to lvl 10 yesterday (+425 hp tune) and it smoked like all hell. so higher the tune more smoke it blows. thing is it doesn't do it when it's cold only when it's warm and only when your sitting at a stop light and such. truck in drive and not moving. put it into park and it's fine. i know it's easy to say injectors but normally it would do it cold as well if it were injectors. any ideas?
