I haven't researched any of them but I wouldn't go with anything that can't be atleast data logged with a wideband if you plan on tuning any of this yourself.


I think dyno's about about worthless for tuning a bike that goes 180mph and have time and effort put into the ram air set up. you need data from that 180mph to look over later if you want to have anykind of a tune with these add on things.
