My Indy recommends Xied's over the piggy back systems. Says he doesn't like the ecu having to constantly readjust itself for them. Seems to me it constantly needs to readjusts the perimeters anyway? My bike runs great with Xieds. Plugs look awesome, more power, sounds great and didn't take a hit on mpg

I don't know. I've had bikes with Power Commanders III's, SERTS, Power Commander V's, and truthfully, they didn't do very much at all. Some caused me all kinds of headaches. Some made my bike run much worse. I've been told by several HD techs and independent mechs, one with over 30 years experience, that bypassing the 02 sensors isn't a good thing to do. My current bike runs great on the simple dealer download. I had all sorts of problems with the "tuners", so I decided to forgo those this time. I'm perfectly happy with the download. Works fine for a simple stage one (slipons and airbox). Everyone I talked to said the download is absolutely fine for a stage one. Everyone except people on internet forums anyway! 
Maybe if you plan to do more than that, a tuner might help. But, seriously, I know dozens of people running the download, some for lotsa miles and lotsa years, and they had zero problems and are perfectly happy with their bikes. But, spends ya money anyway ya likes!
