I usually literally FELT the change within about 5 seconds (FELT the change when making drastic changes.. ie, mainscale) What kind of rpm ranges and fuel adjustments did you make to smooth your idle? When I start my car I have to give it some gas until it gets going (about 10 seconds or so around 2krpm.. otherwise it either dies or idles up and down real low) I tend to sit slightly lean once its warm and idling (around 15.xx)

I think the giving it gas is a vacuum condition I have yet to figure out (since I changed over to an aftermarket BOV I believe..)

I'm at about 18.5 on the mainscale for my 450s.. none of the rpm ranges have negative values, so I know I havent leaned it anywhere..
