Throttle pop at 1500 continued now just through right TB

[Colorobo]

I have a little stumble pop at right of throttle under load really small and only if i slowly roll the throttle.  If i open it faster it seems to be fine.When im on the gass its good.  I used that Titanium cans tuning I posted. I used the 2002-2003 version. Everything smoothed out awesome Checked valve lash .006 intake 0.008 Exhaust.CO trim is at +5 I had some problems getting it there but will get it to 0 again forgot how I did it, had to use Scura in the preferences. I will try the 2001 version is has a larger baseline throttle setting almost a degree more and see what that does but I'm almost there.Or ill try to adjust it out with the air screws. Or I can connect the 2  vacuum ports like the were originally. Thanks fro everyone's help and Merry Christmas. Rob
