Hello guys! I'm new to the forums and I hope to be some help as I grow an older 4runner owner. The stereo department I can definitely help out with for now...

Anyway, does anyone know if there is a way for us to adjust the idle? I own an '09 Urban Runner and I just got my stereo system installed along with my H.O. alternator.

I'm idling right now at about 600 RPM when warm, but I want to bump it up to about 800-900 so my H.O. alt will keep my voltage up higher when I'm playing my music full tilt at idle.

Is this something that the dealer has to do via computer?

Everything is running just fine, I just want to turn it up a bit...
