I know my tune is way off. IM studying several post to learn. My truck will idle really low in drive gear. I have to peddle it to keep it from dying out. Along with stumble if i do not assist or gear it down to 2nd or 3rd to keep the rpm range high. I couldn't build boost until i realized i needed to mess with delta airflow a few hours ago lol. all help is appreciated.
