Default 07 Roadliner Backfire

I have an 07 Roadliner S with the yamaha drag pipes. It backfires on deaccel frequently. Dealer has been trying to fix and in contact with factory. They have checked for exhaust leaks, changed the air/gas mixture via on board computer, tried using a power commander, put in hotter plugs...still backfires. Any suggestions or anyone with similar problem.
thx
