    Lowering Idle by 500rpm

    I could use some help. New to HP Tuners. If I just wanted to adjust my idle would I only have to make changes to Engine/Idle/ Base Setpoint tab? Will I have to make changes anywhere else as well?

    Thx

    There are 4 or 5 tables that need changing. But if your idle is so high that you need to lower it by 500rpms and you're not asking for that high of an RPM, something else is wrong.

    Indeed.

    Are you stock and what is it idling at cold/hot?
