I have a 2011 Kingpin with Stage 1 slip-ons and K&N filter. Went to dealer for download today. Tech says Stage 1 download for 2011 slip-ons no longer exists in the system. He downloaded the flash for a 2011 Kingpin with Vic Drag Pipes. Says it may run a tad rich with that download for slip-ons. I think that's great as Vic motors are HAPPY running a LITTLE rich. On way home I'm thinking.... Is the flash for slip-ons no more because they don't like Cat-Cons? Do Vic Drag Pipes have Cat-Cons ("Off-Road/Racing Only")? If the download is for pipes without Cat-Cons, should I drill mine out?
