Not much compared to just using the right Keihin Jets. It comes with a different tapered needle which may be nice.. and a lighter spring. But, you can shim the stock needle and clip the stock spring and get pretty much the same affect.
I did the above before getting the dynojet kit. Then for S&Gs I bought the DJ kit... Hardley noticed a difference for the "free" mods. So, it would be nice to be able to get just the needle for $15.. maybe Alba will have one for sale seperate one day.
