Need help with turning up the fuel.

[mazda diesel]

Okay, I have a truck with the 4d55t and I have turned up the fuel on it some, but I do not like the high idle I get when I do it, so my question is how do I turn it up and still have a lower idle?
any help would be appreciated
Thanks in advance

Just turn the idle screw back down, it's on the front of the pump. Also, do the on boost fuel mod.
