I was looking to lower my RPM at idle a little. I was wondering if that's only controlled in Tuner Pro in the tables with "Idle RPM vs Coolant Temp. I have the RPMs all set to 750 at temps over 111* but it seems to only go down to around 850RPMs.

 

I think this is only part of how to control idle quality.. I remember setting this a bit lower than what I wanted.. I'd have to verify ... If you have the ability to emulate, try just fooling around with this by putting, say, 650 and see what happens.

Also what is your TPS %? Should be 0.54 volts.You set this by adjusting the screw on the driver's side TPS sensor.

 

My TPS is set to .55 volts, I'll try burning a chip with a lower RPM in the "Idle RPM vs Coolant temp" Thanks

 

Check the IAC steps that they aren't going to zero. If so then either the IAC is bad or the throttle blades are open too far.

In P/N there is an idle speed adder. This will increase the idle.

There are also the deadband values. This allows for the idle to vary from the desired value. This prevents the IAC from continuously hunting.
