dsm link v3 tuning help :/

[M1L3S]

im honestly not giving myself enough credit here. I know a little, but im just scared to really attempt anything on my own, its like im playing the childhood game of operation, and everytime I go to do anything or adjust it I hear that "BZZZZZZ" sound in the back of my head lol

would just feel more comfortable with someone who knows the ins and outs answering questions as I go about it.

I rather be really cautious now and ask 101 questions to get the right answers then dick around and destroy my car :/
