is it normal for my rpms to stay unstable while idleing? ive heard that with turbo chargers or some other heavy mods this is likely, dont know if thats right or not.

I noticed after I put my tunable induction on the idle was a bit more rough, but it's not drastic at all. I still think my computer's not used to the intake yet.
