2006 Lowrider, open air filter V&H straightshots with quiet baffle.
Been tuning with VTune 3. Made suggested changes in EGR values. Some VE and spark change recommendations were made. Went from 40 mpg to 46 mpg. BUT I have a stumble in the 2000 to 2600 RPM, 20 to 25 mph 1st through 3rd gear area. Specifically targeted this area with Flight Recorder and got no EGR change recommendations from VTune 3.
What else should I be looking at?
Thanks
OK made some adjustments and all is well!

 

What did you adjust to get rid of the stumble?

 

I opened the tune up with the software and noticed in the rpm range and the MAP positions where I was getting the stumble, I was very "rich" (13:1). So I adjusted those areas to 14:1, re-flashed the ECM and the stumble was eliminated.
