how to set idle rpm in tunercats?

i wanna reprogram the car to not idle at 900 rpms because its rediuculously loud and whiny with my blower and takes away all chances of passing of somewhat of a sleeper, what table can i use to program the idle rpm?

You need to change the "IAC Target RPM vs Cool temp".There are two sets of tables P/N and Drive

Just change them both to be equal for the rpm range you are wanting your idle. I'm guessing, but I bet a manual uses the P/N table since there is no load at idle when in P/N or if you have a manual.

That is all that is changed in my tune from PCMforless and have no issue with it idling. The other table looks like it is for strictly for a auto and is unchanged.
