Slight hesitation from idle

It's not a big deal, but something that I would like to fix if I can.  After the car is warmed up and I ever so slightly push the gas pedal, I get a small hesitation and it goes a little lean.  Is there any way to tune this out?  I have the 30003.  I tried to post a video, but it was too large for this site.  Thanks,

How long have you had the system on the car (is it still learning)?  Watch your AFR and if it goes lean first then rich, you need to increase the accelerator pump settings because it's reading the lean and overcompensating pouring fuel to make it rich.  Mine did the same thing, I ended up in the 40 range on almost all my accelerator pump settings, which as I understand is a bit extreme but worked on my truck.

Hi, I am having an issue with stumble of idle as well. When i mash the pedal the engine dies, on slow throttle inputs it runs fine. in my carb experience this would indicate the acceleator pump needed to adjusted to correct the lean condition. the system only has about 20 miles on it. should i just keep driving it so it self learns? I also have no idea what values to start changing.

More driving definately helps.  Drive normally and let it learn.
