Xied/fuel management question...

[JustDave]

So today, I decided to take the bike in to have a set of cycle shack slipons (2 1/2 OD) and an arlen ness big sucker to round out the stage 1. hopefully this will let the bike breathe and give more power (and COOL it off a little)

I currently have a set of Xied's on the bike. (They work like a charm for those who know about them (basically they trick the bike into staying open loop to richen the fuel mixture to 13.8 fuel mixture from the stock mixure)

my question is... am i really going to need to do the download and or power commander route or can i skip it since i have the xied on?)

i put this is softail section because the bike is an 08 heritage (flstc)
