i need a tune

i’ve got LS1Edit and have no clue what in the hell i am doing. a buddy of mine (who knows more than i do) played with it for a little bit and it is idling better and doesn’t smell like a fuel spill anymore, but it does this weird surging thing when i am idling down the road. being that i have no clue what in the hell i am doing with it i am a little affraid to start pissing with stuff. i also have no idea where to set the shift points at or how to do it. so if anyone in here has any knowledge of LS1Edit or tunning in general i would hugely appreciate a little help. thanks guys.
