Have you increase B1602 as well?

You may increase it till it literally increases the rpm past your set RPM.

I found that if i start at .4 at -40 and work down to .325 at 92 and 104 my idle is relatively smooth.

At one point i had it start at .6 till the same .325 and it increased my rpm by 200 durin cold idles. I lowered it till my desired rpm was meet through the warmup cycle...
