It's all n the written interpretation and my punctuation. I said it was NOT lean, as you stated. So I agreed with you.
I just reread this thread this morning. I missed the fact that the issue was on decel braking. I'm not saying it isn't a tune issue as you likely would benefit from a real tuner so you can adjust timing and fuel more accurately. Probably not lean at light throttle as ke5rbd stated. Probably a bit too rich, but may be lean at other areas which is why a good tuner would benefit you.
12hdrk Now just where did you get that I said it was too lean at idle. Below is my post. If you leave the VE settings too near stock when you change cams it will be too rich. Stock runs in the 80's below 2000 and more over lap cams run from 70's to 50's depending on the overlap and other mods. I do agree with what you said other than the too lean part.
"My guess would be the tune is too rich at idle. Not familiar with the Fuel pack settings but any area below 2000 rpms is going to need to be 10 to 15% leaner than stock and the wide open area 5 to 15% richer above 2500 when wide open. You can also get sounds out of the breather with cams. It is actually on split over lap blowing back into the breather and will make sounds. Only does this at idle area and usually just when cold. If I knew more about the fuel pack may could help with settings."

[QUOTE=12hdrk;12225200]Thanks for the clarification. Reading comprehension is not always one of my strong points. I have a daughter that is an English teacher and she didn't get it from me.

presume you installed new cam chain tensioner pads with the install. I would look at three areas:
1. make sure you have the correct map for you set-up. a pinging sounds is more like nickels being thrown at a fan blade sound vs a chain slapping.
2. check the pushrods to make sure they are not hitting the push rod tubes.
3. I would suspect that the setup is quieter in the cam area than you had before and you are now hearing other noises that may have been there but masked with other noises. If you are decel and hear the chain slapping, it sure sounds like primary chain slack. Have you check the tension on the chain/chain tensioner on your primary?

IMO after spending nearly $800 on the Powercomamder 5 with an Auto tuner and having had a TTS master tune on an old bike. My 12 fltrx ran the best and got the most bang for my buck with the SE Race tuner (the non street legal version) and a $250 dyno tune at the dealer. I ran the 254e SE cams in my 103 and made over 100ftlbs it was fun and got out of the hole real fast. I would have saved a lot of money and hastle just buying the SE tuner right Out of the gate. The piggyback tuners are junk the '09 and newer computers arent built to work through a piggyback tuner so you're always half a step behind. For instance most of the piggyback tuners can't do anything about the auto compression releases or modify how the stock o2 sensors work. The SE race tuner can.
Just my option.

Update - tuner upgraded too
Well, after riding a few hundred miles on with the new cams and the fuel pak, I broke down and bought a PowerVision PV-2 from Fuelmoto. Bike ran ok on the fuelpak but felt like I wasn't getting the full benefit of the new cam upgrade. Flashed the tune tonight that Fuelmoto sent and setup the unit to try the auto tune as soon as the weather breaks.
Also changed all oils, and checked on that noise from the primary. I didn't think there was a problem but it had been 10k miles since installing the Hayden primiary chain tensioner and I was curious. Shoe looked good and I added a 1/16" shim to put a little more tension on the chain. Maybe quiten it down a bit. Putting a used fuelpak up for sale if all goes well.
