maybe I need to replace the gasket/s at the slip-on / header pipe. I'm thinking this might be the case. maybe it's sucking in a little air at that joint under decel. though I'll check the other crap before I take off the slip-ons. not a difficult task, just a bit of a pain.

Don’t you have a Harley? Do they use the same copper donut exhaust gaskets as ricers? If so they’re a one-time deal, once the seal is broken you might as well pull the header and replace all four, er two
. They rarely ever reseal.
Your EFI will probably compensate for the leaner condition in the cylinder but you’ll still get much better exhaust flow with the header properly sealed at the cylinder head.
