I picked up my Ultra today. I had Vance and Hines Power Duals with Vance and Hines Basic slip ons added, a Zippers Max flow air cleaner and a Power Commander installed. The baseline dyno was 85HP and 95 Torque. After the additions is was 92 HP and 107 torque. I am really pleased after riding it. Coming home down the freeway I went from 75 to 100 and didnt notice until I looked down, it really feels like it just keeps pulling. The printer was down but he saved the file from the dyno and I will post it when I get it

after riding the bike a few days, an what a great difference, I love it, I have noticed a small amout of popping on decel, not a loud backfire, just an occasional pop pop, only happens when I let off the throttle like going down a steep grade. Is this normal or does the guy that tuned it need to revisit the tuning?

Let the guy who tuned it tweak his map a little.  With some exhaust systems it is pretty hard to eliminate all the popping, but I would think your combination shouldn't be a problem.  Let him know what conditions cause the problem, as in what rpm, coast down only or also on upshifts, etc.

It could be your tune needs a bit of touch up - Or it could be you have a small air leak at the intake or exhaust...

The tuner can go in and add some fuel back at about 1000-2000 rpm  in the 0 percent column and it should take care of it.  In the SERT / TTS you can go into the deleanment tables and adjust there to remove the decel popping.
