from OP: "... bought a 2nd hand dyna fatbob and the bike runs good but a bit of popping on deceleration."
You picked a great bike - congrats! One thing you might look at are the header pipe flange nuts. If they haven't been snugged up in a while there could be some leakage causing the popping you are hearing - only takes a minute to check and doesn't cost you anything. Hope you get it worked out.

short shots are known for popping. I've never had a fuel pak so I don't know how it works with O2 sensors or not. You should give vance and hines a call to find out. Alternately FuelMotoUsa offers 100 to 150 cashback for trading in any fuel tuner. Best bet give them a call they will get you on with someone and you might even get your answer about the fuel pak from them.

fuel pack is a v&h product too use on their pipes. they don't like to mixed with other pipes, some after market units are adjustable , try a you tube search, FOR top performance and tuneabillity you need some thing like a dyno jet that your maps can be tunned for indavigull bikes... Back fireing can be a bit removed by running a bit rich,, Most causes are air leaks at muffler joins/exhaust flange,, ads too character,
