Stumble right off Idle after finished project

EFI Sportster Motorcycle Talk (2007 and up) - The Sportster and Buell Motorcycle Forum - xlforum.net
2009 5000 mile 1200 Nightster, clean throttle body, no intake leaks, Ngk plugs gapped at .40, screamin eagle intake, Firebrand 52 Two into One header, power commander V and G2 quick throw throttle, 29 tooth front pulley,all electrical connections checked and tight, some of the Power Commander maps runwell with just a tad of a dead spot around 2-5% throttle, I have a couple other maps that that include accel pump feature and they choke off idle bad almost stalls, the Bub 7 series PCV canned map runs the best with a small dead spot off idle in some gears, add fuel take away fuel does not seem to fix it, adding 5% for 90 seconds using start up feature gets rid of the Nightster dredded cough and sputter during cold idle, any Ideas
