Ok, so I want to add a Hypercharger, just cuz they look so frickin cool IMO. I have an 06 Softail, 88 cube stock mill. My bike has the full race download from HD, stage 1, and Vance and Hines short shot pipes. I was told two different things. One by my local H-D dealer, and another by a private guy. H-D shop told me I wouldn't have to do anything but add the Hypercharger because of the race download. On the other hand, the private guy told me I needed to add a Power Commander, or a SERT. I tend to lean towards the private guy, cuz I know the guy is good at what he does.
It's the cotton HD air filter. The back of the stock assembly was replaced by this filter and a different base. It's all open behind the chrome cover. I've been told this was the "stage 1" kit.
I agree with your HD source, if you had a Hi-Flow AC on when the stage 1 was performed, assuming they recalibrated the VE's, you probably don't need to do anything more. The difference between the stage 1 kit AC and the Hypercharger isn't enough to warrant a retune IMO.
HD's download are designed for HD's stage I air filter. If you go to one that is more free flowing than the HD one, your bike will be running leaner than it is. Obviously with me being a tuner, I always recommend fuel management and a tune. At the bare minimum, I would have bike ran on the dyno and have some air fuel checks done if you decide to try to run the download. But if you are considering the SERT I say go for it.
